If you're looking to play classical or folk tunes, try a diatonic accordion. Additionally, some might opt for the traditional design while others may want something more modern or custom-made. It’s also beneficial to study popular pieces as well as traditional music from your region; this will allow you to have a broader understanding of music in general (and specifically accordion). There is a wide range of price points available so make sure you shop around in order to find the right one for your budget. This makes the sound different from that of a piano accordion because the buttons produce a square wave rather than the smooth tones made by piano keys. You should familiarize yourself with the buttons and keys on your accordion, as well as its range of sounds.
