There appears to be an issue in omitting dyads (chords) in the notation viewer when attaching attribute 'ped, as in this example: '((q c4 e3e4 ped) (q g3 c3c4 ped h e4 ped) (q c4 ped g4 e4e5 ped)) Similar issues occur when using the attribute-series function: (setf mat '((q c4 e3e4) (q g3 c3c4 h e4) (q c4 g4 e4e5))) (attribute-series '((- 1) (ped 2) (ped 4) (ped 1)) mat)

Hi people, Though I've been using Opusmodus for about 2 years now, and in great love with it, I haven't really had a chance to share my work on the community. But here I have my piano piece vastly written with Opusmodus, and guess what, it's got a cool video, too! Yamaha corporation kindly offered me to use their automated piano for filming, and I think an algorithmic music like this goes very well with it! Yuichi

A piano piece composed this year in February. SB.

Dear Friends, I'd like to share a composition all made in Opusmodus. The composition is part of the Portfolio of my Doctoral Dissertation. I'd like to thank you so much, Opusmodus and the support of you here in this forum was amazing !! Love you all !! TURING PIANO (Julio Herrlein) Here is the commented code for the First Section: ;;;PART A ;PITCHES – The pitch structure are based on "chevron-like" patterns. This can be related to some Xenakis ideas: the arborescences, the music as a plot idea. (setf patpit (integer-to-pitch (gen-integer-step 0 68 '(1 -2 3 -4 5 -6 7 -8 9 -10 11)))) (setf patpit2 (integer-to-pitch (gen-integer-step 0 68 '(11 -10 9 -8 7 -6 5 -4 3 -2 1)))) ;;; This interval pattern leads to an infinite ascending movement, like the picture below: ;;; After that, I decided to restrict the ambitus of the pattern, otherwise it goes ascending forever. I did the restriction thinking in the hands of the pianist, in a way to not collide or crossing the hands. ;;;After the ambitus restriction, the next step was find some partitions to make some chords for the piece, so each hand have a diferent partition of the chevron-like pattern, like below (setf pitpartition (ambitus '(g3 c6)(chordize-list (gen-divide '(1 1 1 3 1 1 1 2) patpit)))) (setf pitpartition2 (ambitus '(g1 g3)(chordize-list (gen-divide '(2 1 1 1 1 2 1 1 1 1 1 1 1 1) patpit2)))) ;;; Next, i decided on the Rhythms to use. The rhythms are complementary, i.e., each hand plays on the silence of the other, using the following pattern: DIGRESSION: The FORTE NUMBERS are part of my dissertation that makes the conversion of the entire Forte sets onto Rhythms modulo 12. The dissertation (in portuguese) can be downloaded HERE: Das alturas ao ritmo : teoria dos conjuntos rítmicos como ferramenta composicional From pitches to rhythm: rhythmic set theory as a compositional tool. http://hdl.handle.net/10183/179457 Abstract This doctoral dissertation is divided into two parts: the first deals a rhythmic set theory, and the second contains the portfolio of compositions developed during this period of studies. This dissertation presents a system of rhythmic organization parallel to the musical set theory pitch class organization FORTE (1973), as well as an adaptation of the time-point-system (BABBITT, 1962). From the standpoint of the traditional set theory, and also from the diatonic set theory, this unified approach allows to estabilish a connecting tissue of basic aspects: from the harmony and chords symbols to the rhythmic organization. At one time, in a complete catalog, the families of pitch class sets and chord symbols are related to their respective rhythmic counterparts. The musical motivation for this research came from my interest in the swinging and groovy repetitive rhythms called timelines (TOUSSAINT, 2013), commonly used in popular music. These dancing timelines have properties similar to those of the diatonic sets, and for this reason, this dissertation presents some properties of the diatonic pitch class sets, drawing a parallel with their rhythmic counterparts. These relationships also appear in the portfolio of compositions, characterizing some procedures used. The portfolio of compositions, which includes a composition for symphony orchestra, is presented form the standpoint of a duality between transparency and opacity. This duality address the essential differences in the audibility of the results from various composition techniques. This study of Rhythmic Set Theory will serve as an analytical approach of my compositional output in popular music, with a systematic way to understant and to extrapolate some aspects already used in my practice as composer and improviser. Here is the rhythm used in Turing Piano (with Forte numbers and rotations) (setf ritmo1 (gen-repeat 10 '(s s -s s s -s -s -s s -s -s s -s s -s -s s -s s -s -s -s s -s))) (setf ritmo1b (length-invert ritmo1 :omn t)) ; DINAMICS: Following the parametric stuff, I decided to set the dynamics, according to the harmonic density, i.e. the more notes, the more louder. (setf din1 (span pitpartition '(p p p ff p mf pp ff))) (setf din2 (span pitpartition2 '(f p p p p ff p p ff pp pp f mf mf))) ;ASSEMBLING of the materials (setf lhmat1 (make-omn :length ritmo1 :pitch (pitch-transpose 4 pitpartition) :velocity din1)) (setf rhmat1 (make-omn :length ritmo1b :pitch (pitch-transpose 4 pitpartition2) :velocity din2)) ;MONTAGE of music blocks (assemblage) (setf pianoassemblerh (assemble-seq lhmat1)) (setf pianoassemblelh (assemble-seq rhmat1)) ;;;SCORE- Layout (def-score Miniatura-pno1 (:key-signature 'atonal :time-signature '(3 4) :tempo 85 :octave-shift '(c2 c6) :layout (grand-layout 'pno :all-accidentals 'all)) (pno :omn (merge-voices lhmat1 rhmat1) :channel 1 :sound 'gm :program 0) ) COMPLETE VIDEO

Hello, a small piece for piano solo. Score script attached to this post. SB. Jeu2PourPiano.opmo

Magic piece for piano :-) SB.

A short piece for piano. Basically, i've played the piano part into logic X, export the part to midi and imported it into opusmodus. After importation, i have copied the OMN piano part from the imported score into a variable named pmat and also the controllers information for sustain pedal (controller No.64) into a variable named ct64. I've generated some scales from a row using harmonic-progression function: (setf row (rnd-row :type :pitch :seed 932281 :transpose 3)) (setf chords (harmonic-progression (rnd-number (length pmat) -11 11) row :size 7 :step 1 )) and finally i've applied this harmonic structure with tonality-map function onto my piano material (variable pmat): (setf piano (tonality-map (mclist chords) pmat)) and exported back the resulting midifile to Logic for further edit and piano score edit. SB.
