How many notes?
To start, a handpan with 8 or 9 notes (one ding plus 7 or 8 notes around it) is ideal: enough to play real melodies without drowning in options. Instruments with 10 notes or more, or with bottom notes, are aimed at more advanced players. On the electronic side, the Neotone comes in a 10-note model and the Mutant in 19 notes: you start simple and keep room to grow.
