V7 CHORD: Add a minor 7 th to the root of a V triad (or a minor 3 rd above the 5 th ). The V7 chord is a chord and not a triad because it has 4 notes rather than 3. Often, the 5 th of a V7 chord is omitted. The V7 chord then has the same number of tones as the I and IV chords while still retaining the quality of a 7 th chord. Commonly called a Major–minor 7 th

TRIPLETS: When three notes are grouped together with a figure “3” above or below the notes, the group is called a TRIPLET. The 3 notes are played in the time of 2 notes of the same value. Counted: 1 trip – let, 2 trip – let Counted: Trip – a – let, etc.
INCOMPLETE MEASURES (PICK–UPS): Some pieces of music begin with an incomplete measure. This note (or notes) is known as a PICK–UP note. The beats that are missing in the first measure are “made up” in the last measure, often meaning the last measure will have fewer than the required number of beats.
SYNCOPATION: When the accent in a musical passage falls on the weak beat (&) rather than on the strong beat (1, 2, 3, 4, etc.), it is called SYNCOPATION.
