04 / 04 · Quick answers
Quick answers.
01Can I play a song on piano from just the chords?
Yes. Play the chord’s root in your left hand and the chord in your right, then make it your own. Lyrics and Chords puts each chord over the words, so you know where it changes.
02Does Chord Lens show piano chords?
Yes. Chord Shapes draws every chord in the song on a keyboard, lit in time as the song plays.
03Can I hear just the piano part?
Yes. The Piano Stem Splitter splits the song into stems, so you can solo the piano to hear its voicings, or take it out and play the part yourself.
04Can I move a song to a key that is easier to play?
Yes. Change Song Key moves the song up or down at the same speed and re-spells every chord in the new key.
