As you will have worked out. Gamelan notes are named using numbers.
In the 5-note ‘slendro’ scale they are numbered 1,2,3,5,6 and in the 7-note ‘pelog’ scale (if you have the full version of the app) 1,2,3,4,5,6,7
The obvious thing then is to write the numbers down that you played.
Try playing the notes as they are written above.
• What does it sound like to you?
• How much information have you received?
• Do you know if you are playing it right?
