A# Selisir Scale — Notes and Intervals
The A# Selisir scale is the principal pentatonic mode of the Indonesian pelog system, serving as the default sonic world of Javanese and Balinese ceremonial gamelan music. On Tres Cubano, the notes are A#, B, C#, F, F#. Its asymmetric intervals have no Western equivalent, and many gamelan orchestras are permanently tuned to this mode for shadow puppet theater, court dances, and temple ceremonies. Commonly used in Gamelan, Indonesian, World, Ambient. Notable players include Lou Harrison, Steve Reich. Use over drones and interlocking ostinato patterns. Traditional gamelan music does not use chords — the scale supports layered melodic patterns at different speeds (irama).

How to Play A# Selisir on Tres Cubano
Begin by locating A# on your instrument and play through the 5 notes of the Selisir scale slowly, ensuring each note rings clearly before increasing speed.
The A# Selisir scale contains 3 sharps (A#, C#, F#). This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine — Exercises for Playing
Set a metronome to 80 BPM and play the A# Selisir scale in groups of four notes, shifting the starting note each repetition. This builds muscle memory across the entire scale range. After a week, try improvising short 4-bar phrases using only these notes.
This scale works well over simple power chord progressions or a 12-bar blues in A#. Try a A#5 - F5 - F#5 progression. This scale is especially effective in world contexts.
Tres Cubano Tips
Practice the A# Selisir scale slowly and evenly on your instrument, focusing on tone quality for each of the 5 notes before building speed. Aim for a meditative quality in your phrasing to match the natural character of this scale.
