Tuplets Grouplets The standard rhythmic values divide into 2 parts, then 4 parts, then 8 parts, and so on (see Rhythmic Values). Tuplets (also called grouplets) fill in the gaps between these ratios. The word tuplets may be pronounced “tuplets” or “tooplets.” | 20 High-Yield Music Theory Vol. 1 Music Theory Fundamentals Section Tuplets Grouplets Tuplets Grouplets The standard rhythmic values divide into 2 parts then 4 parts then 8 parts and so on see Rhythmic Values . Tuplets also called grouplets fill in the gaps between these ratios. The word tuplets may be pronounced tuplets or tooplets. Triplets Triplets divide a rhythmic value into three equal parts rather than two or four. The triplet uses the rhythmic value for a two-part division the next longer duration. In the example below the eighth note a two-part division is the next longer duration so the triplet uses eighth notes. quarter note 2 parts triplet 3 parts 4 parts - - 3 Quintuplets Sextuplets Septuplets In simple time signatures see Simple Meter tuplets grouplets always use the next longer rhythmic value. Quintuplets five equal parts sextuplets six equal parts and septuplets seven equal parts all use the rhythmic value for a four-part division. Read each staff left to right to see all the divisions. Tuplet brackets Tuplet brackets should be used with the number on the notehead side when there isn t a beam half notes quarter notes whole notes . Only tuplets that use half note and quarter note rhythmic values in the example above have brackets. Chapter 1 Music Notation 21 Duplets and quadruplets compound time signatures In compound time signatures see Compound and Asymmetric Meter duplets and quadruplets look like the corresponding simple meter beat division.

In the example below six sixteenths per beat divided into two halves gives three sixteenths for each half of the beat. Q J J J J J J 8 J -J -J J J J Groups of 3 tied sixteenths -J 2 2 O ũ 1 O 1
