LearnMusicTheory.net 2.11 Nonchord Tones Nonchord tones = notes that aren't part of the chord. Nonchord tones always embellish/decorate chord tones. Keep in mind that many authors use the term "consonance" for a chord tone, and "dissonance" for a nonchord tone. suspension (S) = "delayed step down" passing tone (PT) neighbor tone (NT) 1.

Harmonizing Notes Outside the Prevailing Harmony
Krumbholz, Theory IV Harmonizing Melody Notes Outside the Prevailing Harmony. 1 More than one solution may work with a particular “nonchord” note. Experiment with different harmonizations. Note: several of the chords below may be enharmonically spelled, for ease of reading (for the performer). Use a seventh chord whose root lies a P5 above/below the prevailing harmony: Use a barbershop seventh chord (BS 7) whose root is a m2 below/above the prevailing harmony. Works especially well when the prevailing harmony is a BS 7. Use a BS 7 chord whose root lies a M3 below the prevailing chord: 1 Based on handouts from Burt Szabo and Dave Stevens. Krumbholz, Harmonizing Nonchord tones, p. 2 Use a BS 7 chord that lies a tritone away (“across the clock”) from the prevailing harmony. Use a chord that has the same root as the prevailing harmony • The added 9 th chord, major triads only (I or IV chord only) • The incomplete (or barbershop) 9 th chord; use when the prevailing harmony is a BS 7 chord. • The barbershop (or “substitute”) 6th chord; use when the prevailing harmony is a triad (I or IV chord only). • The barbershop (or “substitute”) 13 th chord; use when the prevailing harmony is a BS 7 chord. Krumbholz, Harmonizing Nonchord tones, p. 3 Use a diminished chord with the same root as the prevailing chord. Works especially well when the prevailing harmony is a BS 7 chord. When a “nonchord tone” falls between two harmonies (such as, say, the last note of a measure), the note will be easier to harmonize if you use the above approaches as applied to the upcoming chord rather than the current one.

As machine learning technique we chose genetic programming, because it is capable of learning formula consisting of both logic and numeric relations. Genetic programming was never used for this purpose to our knowledge. We therefore investigate a well understood case in this pilot study: the dissonance treatment in Palestrina’s music. We label dissonances with a custom algorithm, automatically cluster melodic fragments with labelled dissonances into diﬀerent dissonance categories (passing tone, suspension etc.) with the DBSCAN algorithm, and then learn rules describing the dissonance treatment of each category with genetic programming. As positive examples we use dissonances from a given category.

Third Species Counterpoint (4:1) Heath: Counterpoint (Music 221) Rules and Guidelines
Third Species Counterpoint (4:1) Heath: Counterpoint (Music 221) Rules and Guidelines Four quarter notes of counterpoint are written for each whole note: Beat 1 (Strong); Beats 2 and 4 (weak); Beat 3 (weaker than beat 1, more accented than beats 2 and 4). • Strong beats should not outline a dissonant interval. No more than 3 consecutive measures should begin with the same interval. No unisons should be used on strong beats (other than at the beginning and end). Consecutive downbeats may be 5ths and 8ves, but no more than two in a row of the same kind should be used. • The interval on the first quarter note is always consonant and the interval on the third is often also consonant, while the 2nd and 4th intervals may be dissonant. The third may be dissonant if the other 3 intervals are consonant. • P5s and P8s that occur against two different notes of the cantus firmus should be separated by at least two quarter notes. P5s or P8s with only one intervening quarter note occurring within a measure (i.e., over the same cantus firmus note) are fine. Avoid having more than two consecutive strong-beat 5ths or 8ves. • Leaps must be treated very carefully in 3rd species. Avoid too many consecutive leaps (especially in the same direction). Avoid leaps into strong beats (downbeats especially). Dissonances are allowed on all beats except for beat 1, ONLY if they belong to one of the following gestures: 1. Passing Tone: a dissonance that fills the space between a third by direct, stepwise motion.

A Modular System Generating Jazz-Style Arrangement for a Given Set of a Melody and Its Chord Name Sequence

Sci. & Tech. 29, 1 (2008) #2008 The Acoustical Society of Japan PAPER A modular system generating Jazz-style arrangement for a given set of a melody and its chord name sequence Norio Emura1;Ã, Masanobu Miura2;y and Masuzo Yanagida3;z 1Graduate School of Engineering, Doshisha University, Japan 2Faculty of Science and Technology, Ryukoku University, Japan 3Faculty of Engineering, Doshisha University, Japan ( Received 28 February 2007, Accepted for publication 28 August 2007 ) Abstract: There are many music systems available on the market, such as systems for the automatic arrangement of music pieces given as note sequences for solo pianos into a piano score in a speciﬁc style. These systems, however, are usually designed to generate music by concatenation of existing arrangement patterns, so no one can expect that these systems will satisfy user requirements. We propose a system in which a given melody expressed as a note sequence is arranged into a modern Jazz-style score for the piano on the basis of the ‘‘Jazz theory,’’ a theory of harmony used in Jazz and popular music. The performance of the proposed system is evaluated by comparing the results obtained with the proposed system with those obtained using popular arrangement systems available on the market. Experimental results show that arrangement using the proposed system is signiﬁcantly superior to arrangement using systems available on the market.

Pitch Perception in Changing Harmony

ProQuest LLC. 789 East Eisenhower Parkway P.O. Box 1346 Ann Arbor, MI 48106 - 1346 ABSTRACT The role of harmony in the definition of tonality provides theoretical framework for the hypothesis that harmonic context affects pitch perception. In tonal music, the stability of individual notes depends on the harmonic setting. It seems then reasonable to expect harmonically guided variations in the cognitive representation of tones. With the purpose of enhancing current models of pitch perception, this thesis proposes an empirical investigation of the effects of harmony on pitch sensitivity. In two experiments, nonmusicians performed a same/different discrimination task on two pitches (a reference tone RT and a comparison tone CT) that were embedded in a melody with a clearly implied harmony. Visual cues facilitated the identification of the tones. The main experiment included only stimuli with different harmonic contexts for RT and CT.

Automatic Determination of Chord Roots
University of Innsbruck Institute of Computer Science Intelligent and Interactive Systems Automatic Determination of Chord Roots Samuel Rupprechter arXiv:1601.02546v1 [cs.SD] 11 Jan 2016 B.Sc. Thesis Supervisor: Univ.-Prof. Dr. Justus Piater 12th January 2016 Abstract Even though chord roots constitute a fundamental concept in music theory, existing models do not explain and determine them to full satisfaction. We present a new method which takes sequential context into account to resolve ambiguities and detect nonharmonic tones. We extract features from chord pairs and use a decision tree to determine chord roots. This leads to a quantitative improvement in correctness of the predicted roots in comparison to other models. All this raises the question how much harmonic and nonharmonic tones actually contribute to the perception of chord roots. i ii Contents Abstract i Contents iii List of Figures v List of Tables vii Declaration ix 1 Introduction 1 1.1 Motivation . .1 1.2 Goals . .1 1.3 Overview . .2 2 Music Theory 3 2.1 Basic Music Theory . .3 2.1.1 Musical Notation . .3 2.1.2 Notes and Pitches . .4 2.1.3 Rhythm . .4 2.1.4 Intervals . .5 2.2 Chords . .5 2.2.1 Nonharmonic Tones . .6 2.3 Chord Roots . .6 3 Determination of Chord Roots 9 3.1 Constructing Chords . .9 3.2 Existing Models . .9 3.2.1 Stacking Thirds . .9 3.2.2 Ernst Terhardt . 10 3.2.3 Richard Parncutt . 10 3.3 A New Model . 11 3.3.1 Assumptions and Representation . 11 3.3.2 Deﬁnition .
