Recording of piano (physical, not electronic keyboard) tones and a chord (mostly c in different octaves), made quickly with cellphone with a little bit of noise, hopefully can still be useful.
This was recorded inside my room with a tonor mic. The keyboard used is a very old lenovo keyboard, but it still sounds pretty decent. Feel free to use this wherever you want.
