Half note Half note In music, a half note (American) or minim (British) is a note played for half the duration of a whole note (or semibreve) and twice the duration of a quarter note (or crotchet). It was given its Latin name ("minima", meaning "least or smallest") because it was the shortest of the five note values used in early medieval music notation . In time signatures with 4 as the bottom number, such as or , the half note is two beats long. However, when 2 is the bottom number (including "alla breve", ), the half note is one beat
Note value Any flags always go to the right of the stem. A note value may be augmented by adding a dot after it. This dot adds the next briefer note value, making it one and a half times its original duration. A number of dots ("n") lengthen the note value by its value, so two dots add two lower note values, making a total of one and three quarters times its original duration. The rare three dots make it one and seven eighths the duration, and so on. The double dot was first used in 1752 by J.J. Quantz; in music
