A Dictionary of Music and Musicians/Triplet
TRIPLET (Fr. Triolet; Ital. Terzina; Ger. Triole). In modern notation each note is equal to two of the next lower denomination, and the division of a note into three is not provided for, although in the ancient 'measured music' it was the rule. [See Dot, vol. i. p. 455.] On this account notes worth one third of the next longer kind have to be written as halves, and are then grouped in threes by means of curved lines, with the figure 3 usually placed over the middle note as an additional distinction. Such a group is called a Triplet, and is executed at a slightly increased speed, so that the three triplet-notes are equal to two ordinary notes of the same species: for example—
Beethoven. Sonata, op. 2. no. 1.
Triplets may be formed of notes of any kind, and also of rests, or of notes and rests together.
Beethoven. Sonata, op. 22.
So also a group of two notes, one twice the length of the other, is read as the equivalent of a triplet, provided it is marked with the distinctive figure 3.
Schumann. Trio, op. 63.
In instrumental music, when the fingering is marked, there is some risk of the figure 3 of a triplet being confounded with the indication for the third finger. To obviate this, the two figures are always printed in different type, or, better still, the triplet figure is enclosed in brackets, thus (3). This plan, which has recently been rather extensively adopted, appears to have been first introduced by Moscheles, in his edition of Beethoven, published by Cramer & Co.
