Guitar Bar is a term used to describe a bar or venue that specializes in live music performances featuring guitarists. The two crossword solutions, FRET and CAPO, are both related to the guitar. FRET is a small metal bar embedded in the neck of a guitar that helps create different notes when the strings are pressed down. A CAPO is a device that is placed on the fretboard of a guitar to raise the pitch of the strings, allowing the guitarist to play in different keys without having to change the fingering.
