I’m always happy to offer suggestions on purchasing an instrument!
Here’s my list of recommended practice instruments:
- well-maintained acoustic piano ($300+ estimated cost for a used piano)
- full-size (88 keys) fully-weighted digital piano ($700+ estimated cost for a decent quality piano)
- not-quite-so-maintained acoustic piano
- full-size keyboard labeled touch-sensitive (when you press harder, it gets louder)
I cannot recommend keyboards that are not full-size or do not have weighted keys, or toy keyboards. They are a serious detriment to developing good technique.
