  1. How to apply different voicings over a chord progression Sometimes you have to spread the notes of a chord progression in a very specific way, specially in the case of sectional writing as in the big bands, for example, where specific voicings are used, commonly named as drop2, drop3, etc. All the voicings are based in the initial closed position: - DROP2 is obtained by dropping the 2nd voice an octave below, as shown below: - DROP3 is obtained by dropping the 3rd voice an octave below, as shown below: There are 24 types of voicings as shown in the image below. The rule is to not exceed the octave between two adjacent voices.

See the next correction!!! All the best ! Julio Herrlein An important correction: In order to produce the right voicings is it necessary to sort the notes before transposing, so the Command to make the voicings over the original chord progression is like this: VOICINGS (setf chordprogdrop (chordize-list (pitch-transpose-n droplist (sort-desc (pitch-melodize chordtrp-rpt))))) Now, the right result for the voicing order csd dp2 csd dp2-4
  2. I've been studying HARMONIC-PATH and TONALITY-MAP functions to determine the exact similarities and differences between the two. While I understand the purpose of those functions in principle from reading the documentation and experimenting with different ideas, I wonder if - for educational purposes - someone could briefly highlight the main explicit differences between the two. In the short example below, both functions produce very similar results, so the question may be when to use one function instead of the other. And is it possible to achieve the same result with both functions? I appreciate anyone's advice or insight into this. Thanks! (setf chords '(c4e4g4 c4f4a4 b3d4g4)) (setf voice (gen-repeat (length chords) '((c4d4 e4)))) (setf harmonic-path (harmonic-path chords voice :octave :path)) => ((c4e4 g4) (c4f4 a4) (b3d4 g4)) (setf tonality-series (tonality-series chords :map '(step) :closest 'up)) (setf tonality-map (tonality-map tonality-series voice)) => ((c4g4 e5) (c4a4 f5) (b3g4 d5))
  3. Dear All, Stephane did this amazing and clear example (code below) of how to spread an harmonic progression over a predefined texture. This can be altered to any harmonic idiom. I did some test, using a chorale texture originated from a 12-tone row and also a more jazz-oriented chorale. THE QUESTION IS (For Stephane Boussuge) 1) How the harmonic rhythm is controlled here? In the example, the chord changes every half note. 2) How can I make the harmony changes at every quarter note ? 3) Can I use different rates of harmonic rhythms ?
