I picked up guitar and piano to experiment with digital audio workstations (daws)
I started out on reaper and I found out, when you buy and use something called a midi keyboard (a piano with a usb port, its like one of those table top things, 80$-200$ for a decent full sized, 91 key piano) and hook it up to a daw, you can use something called vsts (aka virtual instruments)
one keyboard can play an infinite amount of vsts, like all types of guitars to ethic instruments t to all types of piano, and it save the cost of studio stuff like a sound proof wall, expensive microphones, acoustics, and wires/converter boxes. it can be a pain to setup sometimes, but the jist of it is plug in keyboard, install cubase, install the optional vsts, add a track and configure the track by selecting an instrument, and then when you play piano it plays like the instrument, then when youre done just export to mp3 (you can save super hq files like this) and save the file lol
