Ritrovare Tricordale

video, music and harpsichord: Alessio Silvestrin

TRICORDALE TRICORDALE composed by Alessio Silvestrin, applies the music composition technique Musica Tricordale, created by Franceso Valdambrini (1933-2007). Musica Tricordale uses the “tricordo bítono” ( trichord of three notes together in the configuration of two tones ). 
RITROVARE TRICORDALE has been composed on one among the systems included in the technique of Musica Tricordale, which is a cycle of 36 notes: 
B-A-G, F#-E-D, C#-H-A, G#-F#-E, D#-C#-H, A#-G#-F#, F-Eb-Db, C-B-Ab, G-F-Eb, D-C-B, A-G-F, E-D-C. 
Such cycle of notes is continuing during the all composition. This composition is written in tempo of 9/8 and divided in three sections and although was originally written for a clavichord, it can be played in other keyboard instrument as well.
The first section presents the melodic material and uses three times the the full cycle of 36 notes dived in six hexachord, each one permuting two trichords within each phrase of two arsis and two thesis till the bar 18.
The second section continues with the cycle of 36 notes divided hexachords of two trichords permuting and retrograding notes of 1/16 value accelerating in series of 11 notes after the arsis form the bar 18 with the hexachord: A-G-F, E-D-C and continue form the bar 19 with the hexachords:
B-A-G, F#-E-D (1-2-3, 4-5-6 ) in the order of 11 notes; 1-5-6-3-4-2-4-3-6-5-1; 
C#-H-A, G#-F#-E (1-2-3, 4-5-6 ) in the order of 11 notes; 1-3-2-6-5-4-5-6-2-3-1; D#-C#-H, A#-G#-F# (1-2-3, 4-5-6 ) in the order of 11 notes; 1-3-4-2-6-5-6-2-4-3-1;
 F-Eb-Db, C-B-Ab (1-2-3, 4-5-6 ) in the order of 11 notes; 5-4-3-2-1-6-1-2-3-4-5; This permutation repeats twice each time ending with the thesis of the hexachord G-F-Eb, D-C-B and than twice by using triplets of 1/16 notes and changing metronomic parameter as well. The third section form the arsis of bar 38, uses the melodic material of the first section with some melodic variation and extends the duration of four phrases of this section with the emphasis of the note C# in the different octaves.
RITROVARE TRICORDALE has been originally composed for clavichord and can be played on other keyboard instrument as well.
