The key of Bb is Bb and Eb; that means the Bb scale is Bb C D Eb F G A Bb. TWO KEY SIGNATURES YOU JUST HAVE TO KNOW No sharps or flats is C major. One flat is F major. IN CASE YOU FORGOT, HERE ARE ALL THE PITCHES A Ab / G# KEY SIGNATURES WITH FLATS G Flats always appear in the key signature in the same Gb / F# order. We call this the ORDER OF FLATS. F / E# Fb / E Bb Eb Ab Db Gb Cb Fb Eb / D# D You will never see Ab in a key signature without Bb Db / C# and Eb. You will never see Cb without Bb Eb Ab Db C / B# Gb. Cb / B Bb / A# For key signatures with more than one flat, the A major key is the next-to-last (second from right) flat. So if a key signature has Bb and Eb, we call it “the key of Bb major;” if you play the Bb major scale, you WHY DO WE HAVE TO LEARN SCALES? will play ALL the pitches in this key signature. If a Most music in the western hemisphere (Europe and key signature has Bb, Eb, Ab, Db, and Gb, we call it the Americas) is essentially scales and arpeggios cut “the key of Db major.” In reverse, to make the “key up and put in a different order. If you look closely at of Gb major,” go one past Gb in the order of flats: any piece of music, you'll find scales everywhere. If Bb Eb Ab Db Gb Cb. you practice your Bb major scale, you get a little better at every piece of music written in the key of Bb major. KEY SIGNATURES WITH SHARPS Sharps always appear in the key signature in the same order. We call this the ORDER OF SHARPS. HOW DO KEY SIGNATURES WORK? A key signature is a series of sharp or flat symbols F# C# G# D# A# E# B# placed on the staff, designating notes that are to be consistently played one half-step (semitone) higher You will never see A# in a key signature without F#, or lower than the equivalent natural notes unless C#, G# and D#. You will never see C# without F#. otherwise altered with an accidental. In other words, if there’s a Bb in the key signature, every B in For any number of sharps, take the last sharp the piece is flat unless it has an accidental. The displayed in the key signature and go up one half- purpose of the key signature is to minimize the step (semitone) to get the major key. For example, number of accidentals required to notate the music. if a key signature has F#, C#, and G#, the last sharp is In principle, any piece can be written with any key G#, so we call this “the key of A major.” If you play www.TubaPeter.com for sheet music, videos, downloads, recordings, and more. 2 the A major scale, you will play ALL the pitches in Eb F G A Bb, so the Bb minor chord (and the Bb this key signature. If a key signature has F#, C#, G#, minor arpeggio) is Bb Db F. Additionally, the Bb D#, A#, and E#, E# is the last sharp, so we call this minor scale is Bb C Db Eb F Gb Ab Bb. Again, the Bb “the key of F# major” (because E# is the same as F, minor chord (and the Bb minor arpeggio) is Bb Db F. F# is one half-step above E#). In reverse, to make the “key of E major,” go down a half-step (to D#), then read off the order of sharps until you reach it: HARMONIC MINOR AND MELODIC MINOR F# C# G# D#. Minor scales come in three main varieties: natural, harmonic, and melodic. HOW DO MINOR KEYS WORK? The harmonic minor (or “minor harmonic;” they are Put simply, major keys sound “happy,” while minor often spoken interchangeably) scale is the same as keys sound “sad.” Every major key has a RELATIVE the natural minor but with a chromatically raised MINOR KEY which uses the exact same key signature (one half-step) seventh degree (pitch). but starts on a different pitch and sounds sad instead of happy. For example, in the key of A minor, the harmonic minor scale is: A B C D E F G# A. The F# minor The relative minor is three half-steps (a minor third) harmonic scale is: F# G# A B C# D E# F#. down from the NAME OF THE MAJOR KEY, regardless of whether it is a “flat” or a “sharp” key The melodic minor scale is played differently going signature. For example, the relative minor key of C up than when it is played coming down. The melodic major is A minor (B is one half-step below C, Bb is minor scale is the same as the natural minor but two half-steps, and A is three half-steps). The A with chromatically raised sixth and seventh pitches minor scale uses the same key signature as the C ONLY WHEN THE SCALE IS ASCENDING (played up), major scale (no flats, no sharps), only starting on A. but is identical to the natural minor when the SCALE Therefore, the notes of the A minor scale are: A B C IS DESCENDING. D E F G A. We call this the A MINOR NATURAL SCALE, to differentiate it from the A MINOR For example, A minor melodic scale goes up like this: HARMONIC SCALE and the A MINOR MELODIC A B C D E F# G# A. But it comes down like this: A SCALE. We also say that A minor is the “relative G F E D C B A. minor key of C major” and C major is the “relative major of A minor.” The F# minor melodic scale goes up like this: F# G# A B C# D E# F#. But it comes down like this: F# E The relative minor key of A major (F#, C#, G#) is F# D C# B A G# F#. minor, therefore the F# minor scale is: F# G# A B C# D E F#.

  • An App to Find Useful Glissandos on a Pedal Harp by Bill Ooms
    HarpPedals An app to find useful glissandos on a pedal harp by Bill Ooms Introduction: For many years, harpists have relied on the excellent book “A Harpist’s Survival Guide to Glisses” by Kathy Bundock Moore. But if you are like me, you don’t always carry all of your books with you. Many of us now keep our music on an iPad®, so it would be convenient to have this information readily available on our tablet. For those of us who don’t use a tablet for our music, we may at least have an iPhone®1 with us. The goal of this app is to provide a quick and easy way to find the various pedal settings for commonly used glissandos in any key. Additionally, it would be nice to find pedal positions that produce a gliss for common chords (when possible). Device requirements: The application requires an iPhone or iPad running iOS 11.0 or higher. Devices with smaller screens will not provide enough space. The following devices are recommended: iPhone 7, 7Plus, 8, 8Plus, X iPad 9.7-inch, 10.5-inch, 12.9-inch Set the pedals with your finger: In the upper window, you can set the pedal positions by tapping the upper, middle, or lower position for flat, natural, and sharp pedal position. The scale or chord represented by the pedal position is shown in the list below the pedals (to the right side). Many pedal positions do not form a chord or scale, so this window may be blank. Often, there are several alternate combinations that can give the same notes.

  • Recognizing Key Signatures Music Fundamentals 14-119-T
    Recognizing Key Signatures Music Fundamentals 14-119-T Constructing the Key Signature: In the last lecture, we connected scales and tonality. We also found that in order to alleviate the labor of writing accidentals, key signatures Figure 1 were created. To review, key signatures are placed immediately after a clef, and they indicate what accidentals are needed throughout a composition, thus those accidentals would not have to be written next to a note in the music [see Figure 1]. Any note that does not have an accidental is considered natural. Key signatures will have either all sharps or all flats. Key signatures with both sharps and flats do not exist. Figure 2 Key Signatures 2 - page 1 The Circle of 5ths: One of the easiest ways of recognizing key signatures is by using the circle of 5ths [see Figure 2]. To begin, we must simply memorize the key signature without any flats or sharps. For a major key, this is C-major and for a minor key, A-minor. After that, we can figure out the key signature by following the diagram in Figure 2. By adding one sharp, the key signature moves up a perfect 5th from what preceded it. Therefore, since C-major has not sharps or flats, by adding one sharp to the key signa- ture, we find G-major (G is a perfect 5th above C). You can see this by moving clockwise around the circle of 5ths. For key signatures with flats, we move counter-clockwise around the circle. Since we are moving “backwards,” it makes sense that by adding one flat, the key signature is a perfect 5th below from what preceded it.

    INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality o f the material submitted. The following explanation o f techniques is provided to help clarify markings or notations which may appear on this reproduction. 1. The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image o f the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand comer of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete.

  • Key and Mode in Seventeenth- Century Music Theory Books
    204 KEY AND MODE IN SEVENTEENTH- One of the more remarkable cultural phenomena of modern times is the emergence of a generally accepted musico-syn- tactical system (a musical "language") known, among other ways, as the "common practice of the eighteenth and nineteenth centuries," or as the "major/minor system of harmony," or as "tonal [as opposed to modal] harmony. " While twentieth-cen- tury composers have sought new ways to structure music, in- terest in the major/minor system continues undiminished owing to a variety of reasons, among them the facts that the bulk of present day concert repertoire stems from the common prac- tice period, and that theories relevant originally to music of the eighteenth and nineteenth centuries have been profitably extended to more recent music. 205 CENTURY MUSIC THEORY BOOKS WALTER ATCHERSON Much has been written concerning the major/minor system. By far the most words have been expended in attempts to codify the syntax of major/minor and make it into a workable method of teaching composition. Numerous music theory text books of the eighteenth and nineteenth centuries fall into this cate- gory. Another category of writing concerning the major/minor system consists of those efforts to set forth philosophical, mathematical, or acoustical explanations of major/minor har- mony; this category often overlaps the first, as it does already in Jean-Philippe Rameau's TRAITE DE L'HARMONIE (1722). In the twentieth century the major/minor system has ceased to serve as a basis for composition instruction, and the search 206 for philosophical, mathematical, and acoustical explanations has proved unrewarding.

  • Phd Thesis, University of Helsinki, Department of Computer Science, November 2000
    5 Quantisation hythm together with melody is one of the basic elements in music. According to Longuet-Higgins ([LH76]) human listeners are much more sensitive to the perception of rhythm than to the R perception of melody or pitch related features. Usually it is easier for trained and untrained listeners as well as for musicians to transcribe a rhythm, than details about heard intervals, harmonic changes or absolute pitch. “The term rhythm refers to the general sense of movement in time that characterizes our experience of music (Apel, 1972). Rhythm often refers to the organization of events in time, such that they combine perceptually into groups or induce a sense of meter (Cooper & Meyer, 1960; Lerdahl & Jackendoff, 1983). In this sense, rhythm is not an objective property of music, it is an experience that has both objective and subjective components. The experience of rhythm arises from the interaction of the various materials of music – pitch, intensity, timbre, and so forth – within the individual listener.” [LK94] In general the task of transcribing the rhythm of a performance is different from the previously described beat tracking or tempo detection issue. For estimating a tempo profile it is sufficient to infer score time positions for a set of dedicated anchor notes (i.e., beats respectively clicks), for the rhythm transcription task score time positions and durations for all performance notes must be inferred. Because the possible time positions in a score are specified as fractions using a rather small set of possible denominators, a score represents a grid of discrete time positions. The resolution of the grid is context and style dependent, common scores often uses only a resolution of 1/16th notes but higher resolutions (in most cases binary) or non-standard resolutions for arbitrary tuplets can always occur and might also be correct.

  • Key Signatures Meters Tempo Clefs and Transpositions Position Work
    The composition criteria for MSHSAA sight reading selections were revised in 2013-14. As a result, the committee determined that it would be beneficial to music directors throughout the state to have this criterion available to assist in preparations for sight reading. With this information in hand, directors will have a better understanding of the difficulty of the selection that will be used and will know what to expect in regard to rhythms, ranges, time signatures, etc. Key Signatures Key Signatures will be limited to the following: C, G, D, F, Bb major and relative natural minors. There should be at least one key signature change per piece. Meters Meters will be limited to the following: 2/4, 3/4, 4/4, Cut Time, 6/8 Tempo Tempi will be no slower than 72 beats per minute and no faster than 120 beats per minute. For continuous pieces, there will be at least one tempo change, but no more than two. Clefs and Transpositions Viola can have limited use of treble clef. Cello can have limited use of tenor clef. Position Work for Strings 3rd position and minimal use of 5th position may be used in the violin 1 part only. Minimal 3rd position work may be used in the violin 2 and viola parts. Half, 2nd, 3rd and 4th position work may be used in the cello part. Half position to the fourth position work may be used in the bass part. Divisi Limited use of divisi parts may be written. Repeats 1st and 2nd endings may be used.

  • Lecture Notes on Transposition and Reading an Orchestral Score
    Lecture Notes on Transposition and Reading an Orchestral Score John Paul Ito Orchestral Scores The amount of information presented in an orchestral score can seem daunting, but a few simple things about the way the score is arranged can make it much more manageable. The instruments are grouped by families, in the following order: Woodwinds Horns Brass Percussion [Soloists, Singers] Strings Within each family, instruments are grouped by type, ordered with the higher instrument types higher within the family: Woodwinds: Flutes Oboes Clarinets Bassoons Brass: Trumpets Trombones Tubas Strings: Violin 1 Violin 2 Viola Cello Bass Notes on Transposition – © 2010 John Paul Ito 2 Similarly, individual instruments within an instrument type are ordered from high to low: Flutes Piccolo Flute Alto Flute Oboes Oboe Cor anglais Clarinets Eb Clarinet Clarinet Bass Clarinet Note that grouping by instrument type first means that the score will not reflect a consistent progression from high to low within instrument families. For example, among the woodwinds, the cor anglais will appear above the Eb clarinet, even though the Eb clarinet has a higher register. For the purposes of harmonic analysis, it is very convenient that scores are laid out with the strings on the bottom. This reflects an 18th-century concept of orchestration, in which the strings served as a foundation, with winds and brass added for extra color. Even into the 19th century, it remains true that all of the information needed for harmonic analysis is found in the strings, at the bottom of the score. This makes analysis easier, because string instruments are not transposing instruments.

  • And the Beat Goes On: Popular Billboard Song Beats Per Minute and Key Signatures Vary with Social and Economic Conditions
    Curr Psychol (2012) 31:313–317 DOI 10.1007/s12144-012-9149-y And the Beat Goes On: Popular Billboard Song Beats Per Minute and Key Signatures Vary with Social and Economic Conditions Terry F. Pettijohn II & Jason T. Eastman & Keith G. Richard Published online: 25 July 2012 # Springer Science+Business Media, LLC 2012 Abstract The beats per minute and key signatures of popular Billboard songs from 1955 to 2008 were investigated along with changes in the social and economic conditions of the USA, in accordance with the Environmental Security Hypothesis. Slower pop songs and songs in less common keys are generally more reflective and serious, whereas faster pop songs and songs in common keys are generally more celebratory and fun. Consistent with theory predictions, songs with more beats per minute and in common key signatures were most popular in social and economic good times and songs with less beats per minute and in less common key signatures were most popular during social and economic bad times. Environmental conditions appear to influence tempo and key preferences of popular music. Keywords Billboard charts . Music preferences . Song tempo . Key signatures . Environmental Security Hypothesis Music continues to be a poplar and increasingly studied topic in the field of social psychology. Previous research (Pettijohn and Sacco 2009) finds longer duration songs listeners rated to have more meaningful content, to be more comforting, more romantic, and slower songs were most popular when social and economic conditions were poor in the U.S. between 1955 and 2003. In addition, researchers (Pettijohn et al. 2010) also found seasonal variations in music category preferences such that energetic and rhythmic and upbeat and conventional music is preferred when partic- ipants are primed with spring/summer seasons.
