<P> Sometimes though that requirement is dropped to create total durations not exactly expressible in the duple system . For example, one might have only three of the usual five sixteenth notes grouped by a bracket marked "3 of 5: 4". </P> <P> Tuplets may be counted, most often at extremely slow tempos, using the lowest common multiple (LCM) between the original and tuplet divisions . For example, with a 3 - against - 2 tuplet (triplets) the LCM is 6 . Since 6 ÷ 2 = 3 and 6 ÷ 3 = 2 the quarter notes fall every three counts (overlined) and the triplets every two (underlined): </P> <P> This is fairly easily brought up to tempo, and depending on the music may be counted in tempo, while 7 - against - 4, having an LCM of 28, may be counted at extremely slow tempos but must be played intuitively ("felt out") at tempo: </P> <P> To play a half - note (minim) triplet accurately in a bar of 4 4, count eighth - note triplets and tie them together in groups of four . With a stress on each target note, one would count: </P>
