A dotted minim.
A whole note is worth 4 beats, a half note is worth 2 beats, a quarter note is worth 1 beat, an eighth note is worth 1/2 a beat, a sixteenth note is worth 1/4 of a beat, a dotted half note is worth 3 beats, and a dotted quarter note is worth 1 and a 1/2 beats.
It's called a dotted minum
A musical note that contains three beats is called a dotted half note.
Anything with a dot is increased by half of the note's value. So if a note is worth 2 beats and it has a dot, then the dot is 1 which then makes the dotted minim 3 beats.
It extends the note for exactly half its value. For example, a dotted half note is worth three beats. Half of a half note is one beat, add that on to the two beats a half note is already worth, and there you have it. Three beats. So, basically we have a half note: 2 We place a dot after it, this dot being worth half its value: 1 It becomes: 3 Half of a half note is not necessarily one beat. These dots have nothing whatsoever to do with beats. If you have a note with a dot after it, the length of that note is extended by 1/2 of that note's length. A second dot means it is extended a further 1/4. Completely irrespective of how many beats there are in a bar.
3 beats
3 beats
In 3/2, a whole note gets two beats.
3 quarter notes beats per measure APEX
In 3/2 time, there are 3 beats in the measure and the half note gets the beat.
Below are a list of notes in the decreasing time values. Every note is worth half of the beats of the previous note: breve, semibreve, minim, crotchet, quaver, semiquaver, demisemiquaver, hemidemisimiquaver etc. The crotchet takes one beat in simple time signatures.
A dot after a note increases the note by half of its original value. Therefore a dotted half note is equal to 3 beats (2+1) in 4/4 time. The second dot is equal to half the value of the FIRST DOT. The value of the first dot of a half note in 4/4 time is 1 beat. Therefore the second dot would be half of a beat, which is an eighth note. Now do the math to put it all together 2+1+1/2=3 1/2 beats. Another way to think of its duration is the equivalent, in 4/4 time, of 3 quarter notes and 1 eighth note.
