A guitarist (or a guitar player) is a person who plays the guitar. Guitarists may play a variety of guitar family instruments such as classical guitars, acoustic guitars, electric guitars, and bass guitars. Some guitarists accompany themselves on the guitar by singing or playing the harmonica.
The correctness of techniques that a guitarist acquires depends on the quality of training. Learning how to play correctly is crucial for any guitarist no matter which guitar he/she plays. (This is true of any instrument.)
The guitarist may employ any of several methods for sounding the guitar, including finger picking, depending on the type of strings used (either nylon or steel), and including strumming with the fingers, or a guitar pick made of bone, horn, plastic, metal, felt, leather, or paper, and melodic flatpicking and finger-picking.
The guitarist may also employ various methods for selecting notes and chords, including fingering, thumbing, the barre (a finger lying across many or all strings at a particular fret), and 'bottleneck' or steel-guitar slides, usually made of glass or metal. These left- and right-hand techniques may be intermixed in performance.
While music is an art form in itself, playing an instrument such as the guitar has long been a popular subject for painters. One of the more famous examples is the painting Degas's Father Listening to Lorenzo Pagans Playing the Guitar by Edgar Degas, which was painted sometime between 1869–72 and is currently owned by the Museum of Fine Arts, Boston.
