The Areta is based on the Indonesian suling instrument as played in gamelan orchestras. The Areta has been designed to approximate the gamelan scales, but to be in tune with equal tempered instruments such as the piano.
The pelog scale has seven tones. For the Areta in G, the seven notes are G, G#, A#, C#, D, D#, F. The pelog Areta has these seven tones, but the tone holes are not all actually reachable! In practice, Indonesian musicians generally choose five of the seven available notes. The most common subsets are named bem and barung. Pelog bem skips tone holes three and seven, whilst pelog barung skips holes one and four. To change between scales, the Areta features a clip that can be used to block one of the tone holes, either three or four. The other hole is skipped by being always closed by the appropriate finger.
The Areta approximates this suling design by having a wooden disc fitted at the mouthpiece, with the PVC cut away for the windway. A PVC clip simulates the rattan ring and is held firmly in place with small rubber bands such as loom bands or hair bands. Spare bands are provided with the Areta.
Note: One photo shows both versions of the Areta. This listing is for the Pelog version.
