1 half
It depends on the time signature. If the time signature is x/4, the the whole note gets 4 beats. It also depends on where the dot is. If the dot is above the whole note, it gets two beats; if it is to the right of the whole note it gets six beats.
A dotted note is 50% longer than the un-dotted note. A whole note is normally four beats. Hence, a dotted whole note would be six beats.
Commonly, There Are Four, Depending On The Length And Dynamics Of The Notes.
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.
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.
In a 4/4 measure it would be 3 beats. =)
A dot beside the note adds one half of the note value to itself. For instance, in 4/4 time a half note equals 2 beats, but with a dot beside the note it would become equal to 3 beats. Another example is a whole note in 4/4 time. The whole note would be equal to 4 beats, but with a dot, it would become equal to 6 beats.
It's just called a half note
It means that length of the note is increased by one half For example: a semibreve is a whole note, and in 4/4 time or 6/4 time (for example) is worth 4 beats. The addition of a dot means that an extra two beats is added to its duration. A minim is worth two beats. The addition of a dot means it is worth three beats. A crotchet is worth one beat. The addition of a dot means it is worth one and a half beats (or 6 quavers).
.... The dot after the note means you add half the beat. As in if it were a dotted quarter note, you would make it 1 and a HALF beats because half of one beat is a half. Or a dotted half note, it would be three beats because it is the two original beats plus half of the note.
The dot at the right of a half note makes the half note one beat longer. The dot makes the note to the left of the dot half of the note value longer. For example a quarter note dot is one and a half beats in 4/4 time.
It adds to the total duration of the note one half of whatever immediately precedes the dot.
