Construction: Guitars typically have a hollow or semi-hollow body made of wood, with a sound hole (in acoustic guitars) or pickups (in electric guitars) to amplify the sound. The body is connected to a neck, which holds the fretboard and tuning pegs.
Strings: Guitars have six strings, although some variations, such as 12-string guitars or bass guitars, may have more or fewer strings. The strings are usually made of metal or nylon and are tuned to specific pitches.
Tuning: Guitars can be tuned to different pitches, typically in standard tuning (EADGBE for six-string guitars). Tuning pegs at the headstock allow players to adjust the tension of each string to achieve the desired pitch.
Playing Technique: Guitar players use their fingers or a pick to pluck or strum the strings, producing sound. Techniques include fingerpicking, flatpicking, hammer-ons, pull-offs, bending, sliding, and tapping, among others.
