Bars are lines drawn vertically across the staff dividing music into measures. The contents of the measure is determined by the fraction at the beginning. The denominator of the fraction shows the kind of notes, and the numerator, the number of that kind contained in a measure. Each measure must contain the number and kind of notes or rests designated by the fraction, or their equivalents.
Artificial groups are groups of notes played and summed in other than their fractional value. The most common artificial groups are the triplet and sextuplet. A triplet is a group of three notes played in the time and summed in the value of two of its own kind. A sextuplet is a group of six notes played in the time and summed in the value of four of its own kind. A group of five notes is played in the time and summed in the value of four of its own kind. A group of seven notes is played in the time and summed in the value of six of its own kind. Occasionally a group of two notes occurs. This group differs from other artificial groups inasmuch as it is played more slowly than the tempo notes. A group of two notes is played in the time and summed in the value of three of its own kind. Artificial groups are designated by a curved line over or under the notes with a figure showing the kind of group, thus:—
triplet
sextuplet
