A rapidly repeated note. If the tremolo is between two notes, then they are played in rapid alternation. The number of slashes through the stem (or number of diagonal bars between two notes) indicates the frequency to repeat (or alternate) the note. As shown here, the note is to be repeated at a demisemiquaver (thirty-second note) rate, but it is a common convention for three slashes to be interpreted as "as fast as possible", or at any rate at a speed to be left to the player's judgment.
In percussion notation, tremolos indicate rolls, diddles, and drags. Typically, a single tremolo line on a sufficiently short note (such as a sixteenth) is played as a drag, and a combination of three stem and tremolo lines indicates a double-stroke roll (or a single-stroke roll, in the case of timpani, mallet percussions and some untuned percussion instrument such as triangle and bass drum) for a period equivalent to the duration of the note. In other cases, the interpretation of tremolos is highly variable, and should be examined by the director and performers.
The tremolo symbol also represents flutter-tonguing.
Enclose a passage that is to be played more than once. If there is no left repeat sign, the right repeat sign sends the performer back to the start of the piece or the nearest double bar.
Denote that preceding groups of beats or measures are to be repeated. In the examples here, the first usually means to repeat the previous measure, and the second usually means to repeat the previous two measures.
|Volta brackets (1st and 2nd endings, or 1st- and 2nd-time bars)
A repeated passage is to be played with different endings on different playings; it is possible to have more than two endings (1st, 2nd, 3rd ...).
(lit. "From top") Tells the performer to repeat playing of the music from its beginning. This is usually followed by al fine (lit. "to the end"), which means to repeat to the word fine and stop, or al coda (lit. "to the coda (sign)"), which means repeat to the coda sign and then jump forward.
(lit. "From the sign") Tells the performer to repeat playing of the music starting at the nearest segno. This is followed by al fine or al coda just as with da capo.
Mark used with dal segno.
Indicates a forward jump in the music to its ending passage, marked with the same sign. Only used after playing through a D.S. al coda (Dal segno al coda) or D.C. al coda (Da capo al coda).
