Note Duration. The length of time that a note is played is called its note duration, which is determined by the type of note. The whole note has the longest note duration in modern music. The semibreve has the longest note duration in modern music. The half note has half the duration of a whole note.
The note duration, which is defined by the type of note, is the length of time that a note is played. A half note is half the length of a full note. The minim lasts half as long as a semibreve. One entire note takes the same amount of time as two half notes.
