Piano Volume Boost

Hello! I play in a jazz combo as pianist. We’re playing Infant Eyes by Wayne Shorter. We were hoping to transcribe the piece, but the piano part is very difficult to hear/pick out chords from the recording. I am new to Audacity and audio processing in general, and was hoping for guidance. I would like either to remove the other instruments (drums, bass, tenor sax), make the piano louder, or have the program pick out chords. Are any of those possible? I know that, especially in this piece, the tenor sits in a range near the piano. Thank you!
