Not angka (literally "number notation" in Indonesian) is a melodic shorthand where numbers 1 to 7 represent the solfège syllables do to ti (1=do, 2=re, 3=mi, etc.). A dot above a number indicates a higher octave; a dot below indicates a lower octave. This system is widely used in Indonesian education, church hymnals, and popular songbooks because it is more accessible than traditional staff notation for those without formal training. For piano, not angka provides the right-hand melody, while chord symbols (e.g., C, G, Am, F) indicate left-hand accompaniment.
