Unlike most traditional instruments whereby they allow you to play every single note of the piano (all black and white notes from low to high), the handpan can only fit so many notes on it, hence the reason why they are sold in different 'scales'. Scales are very simply put, different arrangements of select notes of a piano in a way which people choose to layout on their handpan out of personal preference. That's it. The original handpan community (aka the handpan mafia) love to big-up the supposed significance of one scale over another based on who came up with said arrangement of the notes first or who plays it where but the ultimate truth is that choosing a scale and one which resonates with you the best is entirely up to you. Another variation to a handpan scale is the position in which the notes are placed on the handpan. If you find that your third-highest note from bottom to top is on the left side of the handpan, you might have what's considered a "left-handed" handpan which is like most handpans (and the ones we demonstrate). If however, the third note is on the right, it just means that you have a "right-handed" handpan and that you'll have to start the scale with your right hand.
