Chapter 26 Scales a La Mode CHAPTER 26 SCALES A LA MODE Musical innovation is full of danger to the State, for when modes of music change, the laws of the State always change with them. PLATO WHAT IS A MODE? A mode is a type of scale. Modes are used in music like salsa, jazz, country, rock, fusion, speed metal, and more. The reason the Chapter image is of musicians jamming is that modes are important to understanding (and using) jazz theory, and helpful if you’re trying to understand improvisation. Certain modes go with certain chords. For more information about modes and their specific uses in jazz, read James Levine’s excellent book, Jazz Theory. On the Web at http://is.gd/iqufof These are also called “church modes” because they were first used in the Catholic Church back in Medieval times (remember good old Guido d’ Arezzo?). The names of the modes were taken from the Greek modes, but other than the names, they have no relation to the Greek modes. The two modes that have been used the most, and the only two most people know, are now called the Major and natural minor scales. Their original names were the Ionian mode (Major), and the Aeolian mode (natural minor). The other modes are: dorian, phrygian, lydian, mixolydian, and locrian. Modes are easy to understand. We’ll map out each mode’s series of whole and half steps and use the key of C so there aren’t any sharps or flats to bother with. THE MODES IONIAN Ionian is used in nearly all Western music, from Acid Rock to Zydeco. You already learned it. The Ionian mode is the same as the C Major scale. Use the half/whole pattern you get from the white keys on the piano from C to C: wwhwwwh DORIAN We’re still using only the white keys, remember. The Dorian mode begins on D. The pattern of whole and half steps from D to D on the white keys of the piano is whwwwhw. Do you see where the shift occurred? There are 12 Dorian scales, each starting on a different note, just like all other scales, corresponding to the 12 key signatures. The Dorian mode is a minor-sounding scale used in rock, jazz, blues, and fusion. PHRYGIAN You’ve probably caught on to the pattern by now. Phrygian begins on the third degree of the Major scale and in the key of C is E to E on the white keys of the piano. The whole-half step pattern is hwwwhww. This mode has a Spanish flavor and is used in jazz, flamenco music, fusion, and speed metal. Twelve of these, too. In fact, there are 12 of each type of mode because there are 12 different key signatures, and 12 different pitches in an octave. LYDIAN Lydian begins on the 4th degree of the Major scale and in the key of C is from F to F on the white keys of the piano. Whole-half step pattern is wwwhwwh. You might see this mode in jazz, fusion, rock, or country music. It’s like a major scale with a raised 4th which gives this scale a floating, open quality. MIXOLYDIAN Mixolydian begins on the fifth degree of the Major scale, and in the key of C is G to G on the white keys. Whole-half step pattern is wwhwwhw. This mode shows up in jazz, rockabilly, country, blues, and rock. AEOLIAN Also known as the natural minor scale, the Aeolian mode begins on the sixth degree of the Major scale. In the key of C it’s from A to A on the white keys. whwwhww. Aeolian appears in all kinds of music: jazz, pop, country, Rock, blues, heavy metal, classical, and on and on.... LOCRIAN The Locrian mode has a very exotic and other-worldly sound. All because of the placement of those half steps, in this case, hwwhwww. You’ll find Locrian in fusion and in jazz. The Locrian mode begins on the seventh degree of the Major scale, and is B to B in the key of C. FINDING MODES IN OTHER KEYS There are two ways to find a mode in another key. You can find a mode within a certain key signature, or find a mode starting on a specific note. MODES IN THE KEY OF X To find a mode in a certain key is easiest; there are just a couple steps. 1. Play the Major scale in the key you’ll be using. For an example, let’s say you wanted to find the Dorian mode that uses the key of AB. First step is to play the AB Major scale. 2. Depending on what mode you want, start on the appropriate note in the Major scale, and play an octave in the key of the Major scale. For our example, you want the Dorian mode, which begins on the second degree of the Major scale. So you’d play from BB to BB using the key of AB. MODES FROM A SPECIFIC NOTE To find a mode beginning on a specific note, the process is a little different but still pretty simple. You have a few options, but here’s the best. It’s the best method, because there is only one step, and finding the mode this way relates closely to the chord that goes with it, something you’ll learn in the next section of the book: For this method to be effective, you have to know what degrees of the major scale are lowered to achieve the mode. Let’s try a different mode, perhaps the most common one, the Mixolydian. 1. Compared to the Major scale, the Mixolydian mode has a lowered seventh. So, if you wanted to play B Mixolydian, you’d use the B Major scale with a lowered seventh. That’s it, one step only. 2. But, let’s take the next most common mode, Dorian. Compared to the Major scale, the Dorian mode has a lowered third and seventh. Lower those two degrees in the Major scale and you’ve turned it into a Dorian mode. Easy peasy. MODES USING OTHER SCALES The word mode is a general term. There are modes built from other scales, too, like the ascending melodic minor scale (a scale we haven’t covered). Taking a scale and going through its modes will give you interesting and exotic-sounding patterns of notes to play with. To the right is the “parent” scale (ascending melodic minor) and its third mode, Lydian Augmented. Both scales are used with more advanced harmonic progressions, that are covered elsewhere, but this will help illustrate the concept of modes. There is always something more to practice! MOVING ON Again, modes aren’t particularly necessary to understand music theory in general, but they’re crucial to gain a deeper understanding of jazz theory and especially improvisation. Next we’ll move on to blues scales and many others that sound cool and are fun to play. CHAPTER 26 STUDY GUIDE 1. What are the names of the modes? Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian 2. What mode is the same as the major scale? Ionian 3. Which mode is the same as the natural minor scale? Aeolian 4. Compared to the Major scale, which notes are lowered for the Dorian mode? Mixolydian? Dorian: 3rd, 7th; Mixolydian: 7th 5. What key signature would be used for the Dorian mode beginning on an A? key of G Major one sharp (F#) 6. What key signature would be used for the Mixolydian mode beginning on F? key of Bb Major, two flats (Bb, Eb) PRACTICAL USE EXERCISES 1. Write out all of the modes in the key of F. Learn them on your instrument/voice. Know where the half steps are in each. Then learn all modes in the key of G, then BB, then D, etc. Another way is to learn one mode at a time in every key, for example: D Dorian, EB Dorian, E Dorian, F Dorian, etc..

Non‐heptatonic modes If modes containing seven different scale degrees are heptatonic, eight‐note modes are octatonic, six‐note modes hexatonic, those with five pentatonic, while four‐ and three‐note modes are tetratonic and tritonic. Now, even though the most popular pentatonic modes are sometimes called ‘gapped’ because they contain two scale steps larger than those of the ‘church’ modes of Chapter 3 —doh ré mi sol la and la doh ré mi sol, for example— they are no more incomplete FFBk04Modes2.fm. 2014-09-14,13:57 or empty than the octatonic start to example 70 can be considered cluttered or crowded.1 Ex. 70. Vigneault/Rochon (1973): Je chante pour (octatonic opening phrase) The point is that the most widespread convention for numbering scale degrees (in Europe, the Arab world, India, Java, China, etc.) is, as we’ve seen, heptatonic. So, when expressions like ‘thirdless hexatonic’ occur in this chapter it does not imply that the mode is in any sense deficient: it’s just a matter of using a quasi‐global con‐ vention to designate a particular trait of the mode. Tritonic and tetratonic Tritonic and tetratonic tunes are common in many parts of the world, not least in traditional music from Micronesia and Poly‐ nesia, as well as among the Māori, the Inuit, the Saami and Native Americans of the great plains.2 Tetratonic modes are also found in Christian psalm and response chanting (ex. 71), while the sound of children chanting tritonic taunts can still be heard in playgrounds in many parts of the world (ex.

THE TONALITY OF POPULAR MUSIC AFTER 19601 Martin Pfleiderer While the functional harmonic system of major and minor, with its logic of progression based on leading tones and cadences involving the dominant, has largely departed from European art music in the 20th century, popular music continues to uphold a musical idiom oriented towards major-minor tonality and its semantics. Similar to nursery rhymes and children's songs, it seems that in popular songs, a radiant major affirms plain and happy lyrics, while a darker minor key underlines thoughtful, sad, or gloomy moods. This contrast between light and dark becomes particularly tangible when both, i.e. major and minor, appear in one song. For example, in »Tanze Samba mit mir« [»Dance the Samba with Me«], a hit song composed by Franco Bracardi and sung by Tony Holiday in 1977, the verses in F minor announce a dark mood of desire (»Du bist so heiß wie ein Vulkan. Und heut' verbrenn' ich mich daran« [»You are as hot as a volcano and today I'm burning myself on it«]), which transitions into a happy or triumphant F major in the chorus (»Tanze Samba mit mir, Samba Samba die ganze Nacht« [»Dance the samba with me, samba, samba all night long«]). But can this finding also be transferred to other areas of popular music, such as rock and pop songs of American or British prove- nance, which have long been at least as popular in Germany as German pop songs and folk music? In recent decades, a broad and growing body of research on tonality and harmony in popular music has emerged.

  • How to Construct Modes
    How to Construct Modes Modes can be derived from a major scale. The true application of a mode is one in which the notes and harmony are derived primarily from a mode. Modal scales are used, however, over the chord of the moment in a non-modal tune, although it would not be a modal melody in the strictest definition. There are seven basic modes and you may derive them utilizing a major scale as reference. The names of the 7 modes are: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian Each scale or mode has distinctive note relationships which give it its unique sound. The simplest way to construct modes is to construct a seven note scale starting from each successive note in a major scale. By referencing the diatonic notes in the original major scale (ionian mode), all seven modes can be created from each of the major scale notes. • Ionian is scale degree l to l (one octave higher or lower) • Dorian is 2 to 2 • Phrygian is 3 to 3 • Lydian is 4 to 4 • Mixolydian is 5 to 5 • Aeolian is 6 to 6 • Locrian is 7 to 7 However, there is a better way to construct any mode: To construct any mode, think of the scale degree it is associated with. For example, dorian can be associated with the second degree of a major scale. As we have seen, modes may be constructed by building a diatonic 7 note scale beginning on each successive major scale degree. But you need to be able to construct on any note any of the seven modes without first building a major scale.

  • The 17-Tone Puzzle — and the Neo-Medieval Key That Unlocks It
    The 17-tone Puzzle — And the Neo-medieval Key That Unlocks It by George Secor A Grave Misunderstanding The 17 division of the octave has to be one of the most misunderstood alternative tuning systems available to the microtonal experimenter. In comparison with divisions such as 19, 22, and 31, it has two major advantages: not only are its fifths better in tune, but it is also more manageable, considering its very reasonable number of tones per octave. A third advantage becomes apparent immediately upon hearing diatonic melodies played in it, one note at a time: 17 is wonderful for melody, outshining both the twelve-tone equal temperament (12-ET) and the Pythagorean tuning in this respect. The most serious problem becomes apparent when we discover that diatonic harmony in this system sounds highly dissonant, considerably more so than is the case with either 12-ET or the Pythagorean tuning, on which we were hoping to improve. Without any further thought, most experimenters thus consign the 17-tone system to the discard pile, confident in the knowledge that there are, after all, much better alternatives available. My own thinking about 17 started in exactly this way. In 1976, having been a microtonal experimenter for thirteen years, I went on record, dismissing 17-ET in only a couple of sentences: The 17-tone equal temperament is of questionable harmonic utility. If you try it, I doubt you’ll stay with it for long.1 Since that time I have become aware of some things which have caused me to change my opinion completely.

A term in Western music theory with three main applications, all connected with the above meanings of modus: the relationship between the note values longa and brevis in late medieval notation; interval, in early medieval theory; most significantly, a concept involving scale type and melody type. The term 'mode' has always been used to designate classes of melodies, and in this century to designate certain kinds of norm or model for composition or improvisation as well. Certain pheno­ mena in folksong and in non-Western music are related to this last meaning, and are discussed below in §§IV and V.

MENSURAL NOTATION. In this context the term 'mode' has two applications. First, it refers in general to the proportional durational relationship between brevis and /onga: the modus is perfectus (sometimes major) when the relationship is 3: l, imperfectus (sometimes minor) when it is 2 : I. (The attributives major and minor are more properly used with modus to distinguish the rela­ tion of /onga to maxima from the relation of brevis to longa, respectively.) In the earliest stages of mensural notation, the so­ called Franconian notation, 'modus' designated one of five to seven fixed arrangements of longs and breves in particular rhythms, called by scholars rhythmic modes.

  • THE MODES of ANCIENT GREECE by Elsie Hamilton
    THE MODES OF ANCIENT GREECE by Elsie Hamilton * * * * P R E F A C E Owing to requests from various people I have consented with humility to write a simple booklet on the Modes of Ancient Greece. The reason for this is largely because the monumental work “The Greek Aulos” by Kathleen Schlesinger, Fellow of the Institute of Archaeology at the University of Liverpool, is now unfortunately out of print. Let me at once say that all the theoretical knowledge I possess has been imparted to me by her through our long and happy friendship over many years. All I can claim as my own contribution is the use I have made of these Modes as a basis for modern composition, of which details have been given in Appendix 3 of “The Greek Aulos”. Demonstrations of Chamber Music in the Modes were given in Steinway Hall in 1917 with the assistance of some of the Queen’s Hall players, also 3 performances in the Etlinger Hall of the musical drama “Sensa”, by Mabel Collins, in 1919. A mime “Agave” was performed in the studio of Madame Matton-Painpare in 1924, and another mime “The Scorpions of Ysit”, at the Court Theatre in 1929. In 1935 this new language of Music was introduced at Stuttgart, Germany, where a small Chamber Orchestra was trained to play in the Greek Modes. Singers have also found little difficulty in singing these intervals which are not those of our modern well-tempered system, of which fuller details will be given later on in this booklet.

  • Convergent Evolution in a Large Cross-Cultural Database of Musical Scales

We first define a scale as a sequence of notes (Figure 1A). Scales, sets of discrete pitches used to generate Notes are pitch categories described by a single pitch, melodies, are thought to be one of the most uni- although in practice pitch is variable so a better descrip- versal features of music. Despite this, we know tion is that notes are regions of semi-stable pitch centered relatively little about how cross-cultural diversity, around a representative (e.g., mean, meadian) frequency or how scales have evolved. We remedy this, in [10]. Thus, a scale can also be thought of as a sequence of part, we assemble a cross-cultural database of em- mean frequencies of pitch categories. However, humans pirical scale data, collected over the past century process relative frequency much better than absolute fre- by various ethnomusicologists. We provide sta- quency, such that a scale is better described by the fre- tistical analyses to highlight that certain intervals quency of notes relative to some standard; this is typically (e.g., the octave) are used frequently across cul- taken to be the first note of the scale, which is called the tures.

  • Scales, Modes, Intervals and the Circle of Fifths
    Scales, Modes, Intervals and the Circle of Fifths The word scale comes from the Latin word meaning ladder. So you can think of a scale climbing the rungs of the ladder which is represented by the stave. The degrees of a scale You have to have a note on every single line or space. Each degree of the scale has a special name: • 1st degree: the tonic • 2nd degree: the supertonic • 3rd degree: the mediant • 4th degree: the subdominant • 5th degree: the dominant • 6th degree: the submediant • 7th degree: the leading note (or leading tone) The 8th degree of the scale is actually the tonic but an octave higher. For that reason when naming the degrees of the scale you should always call it the 1st degree. MAJOR SCALES One of the more common types of scale is the major scale. Major scales are defined by their combination of semitones and tones (whole steps and half steps): Tone – Tone – Semitone – Tone – Tone – Tone – Semitone Or in whole steps and half steps it would be: Whole – Whole – Half – Whole – Whole – Whole – Half Major scale formula MINOR SCALES The second type of scale that we’re going to look at is the minor scale. Minor scales also have seven notes like the major scale but they’re defined by having a flattened third. This means that the third note of the scale is three semitones above the first note, unlike major scales where the third note of the scale is four semitones above. A MELODIC MINOR SCALE There are three different types of minor scale: • the NATURAL minor • the HARMONIC minor • the MELODIC minor Each type of minor scale uses a slightly different formula of semitones and tones but they all have that minor third.

CIS 3000: Introduction to Game Design 2 Introduction A scale is an ordered sequence of notes. Typical ly, a scale spans one octave (twelve half steps on the piano roll, ie from C to C) and contains seven note s (eight if we count the repeated note at the octave). Which seven notes we select out of the possible twelve in a one octave range determines what kind of scale we have. Note: there are scales which have more or less than seven notes, but we will only be focusing on those with se ven, or the heptatonic scales. The Major Scale First we’ll discuss the major scale . A major scale is made up of this sequence of whole steps (W) and half steps ( h): W W h W W W h Knowing this sequence is useful because you can create scales regardless of the starting note. Here is an example of a major scale starting on C in both traditional staff notation and Reason’s piano roll notation: You might notice how the re are no sharps or flats in the C scale, or that all of the notes correspond to the wh ite keys on the piano roll. Here’s what the major scale looks like when we start on the D instead: Notice how there a re now two sharps in the scale, corresponding to the two black keys on the piano roll.
