Hi, here's a short score composed for string quartet. All the best to all OM users ! Stéphane stephaneboussuge · Méditation MeditationPourRené.opmo 01 - Conducteur - Méditation.pdf

A.S. Mailbox (three serial miniatures for string quartet) dur: circa 4´30 Composer: Julio HERRLEIN Porto Alegre - Jun/2021 I. Email from Anton II. [SPAM] Re: Hauer III. Letter from Alban A.S. (Arnold Schoenberg) Mailbox are a set of three miniatures for string quartet using 12-tone serial techniques and parametric composition processes. The idea is a imaginary mailbox of Schoenberg dialogues with his main disciples Webern and Berg, and also Hauer, his rival in the creation of a 12-tone composition method. All the pieces are (loosely) based in the same all interval 12-tone row: c4 eb4 a4 db4 b4 ab4 g4 d4 e4 f4 bb4 gb4 PERFORMANCE NOTE: The score and parts accidentals favor the FLATS (b) for easier enharmonic reading. Some of the uses of the tone row are also related to the rhythmic span of the orchestration and the algorithmic method for spreading the tones through the lisp lists in the Opusmodus software. The first miniature “Email from Anton” are inspired by the pointilistic textures used by Webern in his op. 28. In a later section, the textures are intensified by melodic figures and tremolos across the instruments of the quartet. The second miniature “[SPAM] Re: Hauer” is an imaginary email from Hauer (lost in “Arnie´s” spam box…) where he shows to A.S. his klangreihen method (as actually described by Dominik SEDIVÝ, 2011, pp. 25-30) to harmonize and make a smooth parsimonious voice-leading of a 12-tone row. The last piece “Letter from Alban” set up some 6-attack melodic motifs based on the hexachords of the basic row, combined with rhythmic ostinato textures of accompaniment and sweet chords derived from retrograde version of the row. All the best !! Thanks to everyone in this forum who have patience with me ! Julio Herrlein, 2021/JUNE

Here's a short piece for violin solo and Strings ensemble with Fibonacci based harmony. Full score attached to this post fully commented but in French SB. BrinD'or-V04.opmo

Eno/Byrne-esque 'Beat-Betas' as audition tape (i.e. 60 second continuous excerpts). Opusmodus generated MIDI...Mixed as "prototypes" in Logic 9.1.8,'auditioned' in iTunes 'live' to "Audio Hijack Pro".

Hi, here's for study purpose the Opusmodus score of the first movement of my piano trio. All the best to the wonderful Opusmodus users community ! SB. PianoTrio-SlonimskyV2.opmo

Hi, Here's a Strings Trio composed in memory of the victims of Paris attack. Attached Part-a and part-d opmo scores for study purpose. S.B st-a.opmo st-d.opmo

In memoriam to Nigel St. Clair Morgan. RequiemCommented.opmo

Hello, a new piece for ensemble after viewing an Egon Schiele exposition in Albertina museum, Vienna. SB TheSingleOrangeWasTheOnlyLight Partition complète.pdf

Hi, here's the first movement of a work in progress, my strings quartet No.1. OpmoScore attached. You can also find how it was algorithmically made in this forum article/example: SB. Sqrt1-Full-GM.opmo

Algorithmic avant garde jazz improvisation for tenor saxophone, piano, bass and drums. I thought it is time to add something new to our 'Made in Opusmodus' forum. Samples: VSL Ensemble Pro with Vienna Instruments Pro. If you like to study the score, here it is: DADA Quartet.opmo

Hi, for study purpose only, you will find attached to this post the score script of this Prelude for Piano. SB. PreludeForNicolai.opmo
