There are 12, not 10
There are 8 demisemiquavers in a crotchet.
There are eight demisemiquavers in one crotchet beat.
There are three crotchet rests = dotted minim rest.
Half of a dotted crotchet is a dotted quaver.
A dotted semibreve (also known as a dotted whole note) has a duration of six beats in common time. Since a demisemiquaver (or 32nd note) is one 32nd of a whole note, there are 192 demisemiquavers in a dotted semibreve, as it consists of six whole beats, each containing 32 demisemiquavers.
There are 1 and a half beats in a dotted crotchet.
In musical notation, a crotchet (quarter note) is worth 1 beat, a dotted crotchet (dotted quarter note) is worth 1.5 beats, and a quaver (eighth note) is worth 0.5 beats. Adding these together: 1 (crotchet) + 1.5 (dotted crotchet) + 0.5 (quaver) + 1 (crotchet) equals 4 beats in total. Thus, the sum of a crotchet, a dotted crotchet, a quaver, and another crotchet is 4 beats.
A dotted crotchet lasts as long as one and a half crotchets.
A dotted crotchet is worth one and a half beats .
6 semiquavers worth a dotted crotchet
Assuming they are crotchet beats, the note worth three crotchet beats would be a dotted minim.
Assuming they are crotchet beats, the note worth three crotchet beats would be a dotted minim.
