finger should bounce along the head rapidly, producing the roll. Usually, the end of the roll is articulated using the heel of the hand or another finger. Beeswax or rosin is commonly smeared around the edges of the head to assist in the technique. These materials increase friction making it easier to execute. A continuous roll can be achieved by moving the thumb in a "figure of 8" pattern around the head. Popular music Europe Various European folk traditions include the tambourine. The Romani people used the tambourine as a percussion instrument, and it was often passed around the audience to collect money after a performance. In the late 1700s, the tambourine had a surge in popularity in England, with some composers of salon music writing parts for tambourine, indicating as many as 30 different playing strokes or moves. The tambourines of this era often had a circular hole in the frame for the thumb, as one of the moves was to spin the tambourine on the upright thumb. In the late 19th century, The Salvation Army codified the tambourine as one of their important rhythm instruments. They preferred the term "timbrel" which was taken from the Bible. By 1945, Salvation Army performances often entailed elaborate tambourine choreography performed by squads in para-military style, more for visual appeal than for musicality. African American influence African American slaves were denied drums which might be used for long-distance communication. To supply rhythm in music, they turned to smaller percussion instruments such as the bones and the tambourine, as well as clapping and body percussion. The tambourine could accompany the singing of spirituals, and it was used for celebrations and dancing. The tambourine became one of the main instruments of the American minstrel show in the early 1800s, often performed by whites in blackface such as Ned Christy, or sometimes by actual black performers. On stage, the tambourine and bones players in minstrelsy stood to the far left and far right of the Interlocutor (master of ceremonies) and were titled Brother Tambo and Brother Bones: because of their position they were called the end men. The tambourine was also used in some vaudeville acts, including the 1840s dance and musical performances of Master Juba who was able to elicit a wide range of sounds from the instrument including the chugging of a steam train.
