Drum roll

Snare drum roll that are similar to, or precisely like, a concert closed roll include: • American - Multiple bounce roll, triple stroke roll, and crushed ruff • German - Druckruf • Scotch - Buzz roll, stroked rolls 5 through 25 (metered closed rolls in Scottish tradition), and trizzlet • Dutch - Ra stroke • Mexican - Rau Tau and Redoble • Spanish - Redoble de Zumbido • Bajoaragonés - Los Rufaos • Eporedian (Ivrea, Italy) - Rullo The open roll ("double-stroke roll" or "long roll") is played with double strokes alternating between the left and right hands. Using a forearm stroke for the first and the fingers for the second stroke, the 2 strokes can be made to sound identical. This produces a near-continuous sound when the technique is mastered. The 4 Stroke, 8 Stroke, 12 Stroke, 14 Stroke, and 16 Stroke are rare but all exist in official published sources. The Scotch Pipe Band style has a rudimental roll up to 25 strokes. During the American Civil War the long roll called the troops to assemble and signaled an attack. Other than the open roll, there are many other rolls and rudiments that sound like rolls when they are played fast enough (like the freehand technique or single paradiddle).

A tremolo in percussion indicates a roll on any percussion instrument, whether tuned or untuned. A tremolo is notated using strokes, or slashes, through the stem of a note. In the case of whole notes, the strokes or slashes are drawn above or below the note, where the stem would be if there were one. For the case of a snare drum and some other percussion instruments, rolls may be indicated by individual notes or with the use of tremolos, depending on the sheet music's notation. In percussion, three types of tremolos may be seen in sheet music; a tremolo with a single, double, or triple slash going through the stem: A single slash indicates a diddle, or two double strokes from a single hand, that subdivides the note in two. RR or LL A double slash indicates two diddles, or two double strokes from each hand, that subdivides the note in four. RRLL or LLRR A triple slash indicates four diddles, playing two double strokes twice from each hand, that subdivides the note into eight. RRLLRRLL or LLRRLLRR In a time signature, a triple slash quarter note would entail playing double strokes for two eighth notes with a single slash each, or four sixteenth notes RRLL or LLRR. A double slash eighth note would entail playing double strokes for four sixteenth notes RRLL or LLRR. A single slash sixteenth note would entail playing one pair of double stroke thirty-second notes RR or LL. In the case of a half note or whole note, it's common to play alternating double stroke sixteenth notes for the duration of the note. Depending on the sheet music, individual notes with labeled sticking patterns can also be rolls. These rolls can be single stroke rolls, double stroke rolls, triple stroke rolls, or any multiple bounce roll variation. Rolls that don't use tremolos typically incorporate different articulations and dynamics, although this is not always the case. ==See also==
