The Chapman Stick or The Stick is an electric musical instrument invented by the Californian luthier Emmett Chapman in the late sixties. The first models were for his personal use and consisted of 7 and 8 strings. After years of development, the first Chapman Sticks were sold in 1974 with 10 strings. Chapman wanted to create a mix between bass and guitar, which is executed using the "tapping" technique, consisting of playing the instrument by its neck with both hands pressing the strings on the fingerboard. At first he called it "The electric Stick" or "The electric stick". Unlike the guitar, which requires you to pluck the strings with one hand and press them with the other, the stick only requires pressing them using both hands. For this reason, it allows the execution of multiple notes regardless of the pitch distance. This property makes the stick an unusual instrument, as it is compared more to a keyboard than to a guitar. This type of execution allows the instrumentalist to play basses, chords, and melodies simultaneously.
