(musth212) Pitch-Class Sets, Normal Form
The first thing to do with a collection of pitches, a pitch-class set, is to arrange the pitch classes into a form that can be used to compare one set to another. The first order of arrangement is Normal Form, which arranges the pitch classes in ascending order, starting with the pitch class that gives…

(musth212) Atonal Interval Assignment
Due Monday, 3/28: Two-page, IntervalsAssign. Note the added exercise at the bottom of the second page. Use the updated Octave and Enharmonic Equivalence, Intervals post for help. Note that you will have to do some of the assignment of staff paper. It will help you if you combine your answers for questions IV/2, V/2, VI/1,…

(musth212) Late Post: Rhythm/Meter Assignment
I never posted this assignment. If you haven’t turned it in, please do so by Monday, 3/28. Chapter 6 Part A: 4 and 5 Part B: 5 and 6 Remember, to find new tempos in tempo modulation excerpts you follow the formula: original_tempo * (original_grouping_number / new_grouping_number) = new_tempo The grouping numbers will be the…

(musth212) Octave and Enharmonic Equivalence, Intervals (updated)
Moving slowly into non-serial atonality, let’s start with the basics. Octave Equivalence Octave equivalence is really a hold over from basic music theory. We hear pitches in octaves as being functionally the same. C in one register is the same analytically as C in another register. What we’re really doing is still pointing out the…

(musth212) Tempo Modulation
Tempo modulation deserves its own special post, if at least only to fully explain the math used to calculate new tempi. To review, tempo modulation involves a new grouping of some subdivision of the pulse. For example, a quarter-note pulse can be divided into four sixteenth notes. If those sixteenth notes are are accented in…

(musth212) Rhythm and Meter
Brief (very brief) aspects of rhythm and meter from chapter six. Syncopation Syncopation occurs when an accent comes at an unexpected moment, or when an expected event fails to occur. Written and Perceived Meter Sometimes, owing to syncopation, we hear (perceive) a meter that is different from what is written. Changing Meter 20th- and 21st-century…

(maxmsp) amplitude modulation assignment
Due Friday, March 18. Using the MSP Tutorial 9 as your starting point, modify the patcher to allow for envelope control of the modulator amplitude; use a ratio to obtain the modulator frequency; create four different presets. You will need change the expr object in the offset section to a <!-~ 1.> object to use with…

(maxmsp) modulation synthesis in max/msp
This post is not intended as a full explanation of ring modulation, amplitude modulation, or frequency modulation synthesis. The intent is to discuss how to implement various forms of modulation synthesis in Max/MSP. Ring Modulation Ring modulation is the easiest form of modulation synthesis to implement in Max/MSP. You simply multiply the outputs of two…

(maxmsp) extra credit: mapping amplitude entirely in dB
Due Friday, 3/18: For an extra credit grade (40 points, whatever category helps you most), fix this patcher: BasicSynthEnvSusKeyVelocityDB.maxpat Key velocity is being scaled to dB. The function object is formatted to express amplitude as dB (-60. – 0. y value range). Multiplying the key velocity dB times the output of the function-to-line~ will not work.…
