A tenor banjo has only 4 strings and a narrow neck with 17 or 19 frets. At the same time, 4-stringed instruments of other types usually have 22 frets. Learning to play the tenor is quite easy, unlike other types of banjo, because it is tuned to the fifth and is usually played with a flat pick. Tenors are traditionally used in Irish, Celtic, and jazz music and have a rhythmic sound ideal for these styles.
