Are piano chords and guitar chords the same thing?
Chords are three notes played in unison. Since chords are the same universally, yes, you can play the same three notes on a piano to make the same chord that you would strum on the guitar. Find out the three main notes in a particular chord (A Minor, for example) and find the same three notes on the piano. The C chord is C-E-G on the piano. Those are the same three notes you would form with your fingers on the guitar neck. Hope this helps.
