MELATE BINARIO
Solo guitar
MELATE BINARIO for solo guitar is a composition intended to settle the dispute between dodecaphony and diatonicism using the binary system and the popular game of Melate. Faced with the dilemma of being able to use all 12 notes outside the limits of scales, but having to respect a strict order (as required by dodecaphony), or being able to choose the preferred order within a reduced set of notes (as allowed by diatonicism), I found that both languages share the possibility of achieving equivalently effective music.
Thus, odd-numbered pages, which expressed in the binary system always end in 1, are identical in every way to even-numbered pages ending in 0, except that odd-numbered pages are dodecaphonic (using all 12 notes) and even-numbered pages are diatonic (using only 6-8).
Before the concert begins, a Binary Melate ticket is distributed to each person to fill out and put their name on it. The ticket has 8 boxes that must be marked with either 0 or 1. Each box implies the choice of one of the two pages: 1 or 2, 3 or 4, 5 or 6, etc. The total number of pairs of pages to choose from is 8, so the number of possible versions of the piece is 28=256.
During the intermission, the tickets must be collected in a transparent ballot box, so that just before the performance, it is brought to the stage and the performer draws a ticket in full view of the audience, reads the resulting combination, and declares aloud the name of the winner, dedicating the performance of the version they have chosen to them.
Subsequently, in order to read the music, the score is organized by selecting the odd-numbered pages when the marked digit is 1 and the even-numbered pages when the marked digit is 0.
Example: In this example, the digits 11100000 were marked, which indicates that, from pages 1 and 2, you choose the odd; from pages 3 and 4, the odd; from pages 5 and 6, the odd; from pages 7 and 8, the even; and so on.
Pages chosen = 11100000 Odd, odd, odd, even, even, even, even, even. 1, 3, 5, 8, 10, 12, 14 and 16.
