JulioHerrlein Posted October 15, 2017 Share Posted October 15, 2017 Hello, friends ! I'm trying to make some rhythm patterns and I'd like to use the same pattern changing just the time signature order/or sequence. For example, assuming an 8th note as the number 1. 2 2 1 2 2 2 1 (african bembé rhythm) as a pattern. This pattern could match in a 12/8 time signature or also in a 3/4 time signature. This is ok, no problem. But what if I like to span it as a 10/8 + 2/8 or 9/8 + 3/8 or 7/8 + 5/8 or in a sequence like 3/8 + 2/8 + 4/8 + 3/8 always repeating the time signature sequences until have al the notes spanned ? Thanks for help ! Best ! Julio This works for me with ONE time signature only. I need the same stuff with a SEQUENCE of time signatures. (setf padrao '((0 1 2 3))) (setf pitches '((g4 g4 g4 g4 HERE COME THE PITCH LIST, padrao :type :pitch))) (setf lengths (span pitches '(e e -e e HERE COMES THE Rhythm pattern list - same size or less than the pitches))) (setf text (span pitches padrao)) (def-score Stage-1 (:key-signature 'chromatic :time-signature '(4 4) :tempo 80 :layout (treble-layout 'piano-rh)) (piano-rh :length lengths :pitch pitches ;text text :channel 1 :sound 'gm :program 'clarinet) ) Quote Link to comment Share on other sites More sharing options...
JulioHerrlein Posted October 16, 2017 Author Share Posted October 16, 2017 This is even more simple: (setf pitches '((g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 g4 HERE COMES THE Pitch List :type :pitch))) (setf lengths (span pitches '(e -e -e -e HERE COMES THE Rhythm pattern list - same size or less than the pitches))) (def-score Stage-1 (:key-signature 'chromatic :time-signature '(4 4) '(1 8) >>>>>>>> Here is the problem: How to span the content through different Time Signatures using the same rhythm list and pitches ? :tempo 80 :layout (treble-layout 'piano-rh)) (piano-rh :length lengths :pitch pitches :channel 1 :sound 'gm :program 'clarinet) ) Quote Link to comment Share on other sites More sharing options...
Stephane Boussuge Posted October 16, 2017 Share Posted October 16, 2017 for example if you need 3 bars of 3/4 and 2 of 6/8 you can write: :time-signature '((3 4 3)(6 8 2)) you can also separate your length material with gen-divide and get the time signature. Example here: (setf some-pitches (integer-to-pitch (gen-integer-step 0 64 '(2 1 2 3 -2 -1 -2 -1 -2)))) (setf some-lengths (rnd-sample (length some-pitches) '(e e -e e))) (setf some-division '(8 12 8 6 9)) (setf length-div (gen-divide some-division some-lengths)) (setf time-sig (get-time-signature length-div)) (def-score time ( :key-signature 'chromatic :time-signature time-sig :tempo 112 :layout (clarinet-layout 'clarinet) ) (clarinet :length length-div :pitch some-pitches :channel 1 :sound 'gm :program 'clarinet )) SB.

JulioHerrlein Posted October 16, 2017 Author Share Posted October 16, 2017 Thanks a lot, Stephane ! This is great ! And thank you for showing me more functions. However, there some issues: how to control to get a 12/8 instead of a 6/4? Or: how to get always a time signature with x/8 ? Or always with a X/4, or mix them ? In the example you provide, a 12 generates a 6/4 instead of a 12/8. I changed the code a little: (setf some-pitches (integer-to-pitch (gen-integer-step 7 480 '(0)))) ;>>> here, because I want to stay in the same note g4 (setf lengths (span some-pitches '(q q e q q q e))) ;>>> here, because I want this specific rhythm, not random sample (setf some-division '(21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3)) ;here, there's that problem of 6/4 versus 12/8 and one more problem occurred because OM stop changing the timesignature after the number 14 (xml attached) I don't know why. (setf length-div (gen-divide some-division some-lengths)) (setf time-sig (get-time-signature length-div)) (def-score time ( :key-signature 'chromatic :time-signature time-sig :tempo 112 :layout (clarinet-layout 'clarinet) ) (clarinet :length lengths :pitch some-pitches :channel 1 :sound 'gm :program 'clarinet )) Best !!

JulioHerrlein Posted October 16, 2017 Author Share Posted October 16, 2017 I just read now the first line of your message. Thanks, Stephane ! Best, Julio Quote Link to comment Share on other sites More sharing options...
opmo Posted October 16, 2017 Share Posted October 16, 2017 To get the intended time signature: :time-signature '((6 8 1) (12 8 2) (4 8 2)) ; etc... Good example with series of time signature values you will find in Webern 'Variationen Fuer Klavier Op.27, II' score in the Utilities panel: 'Score Examples/Webern'.
