I thought that, when you had a whole note - semibreve in Italian - and the time signature is, say, 5/4, that is still worth 4/4 and, if you use one, you have an extra quarter to fill in the measure. A 6/8 measure should fit three quarter notes (or any equivalent combination), and I am not sure that you can use a whole note in it at all...
Hi Stefano,
You are correct. Whole value has nothing to do with filling the entire measure, although that may happen in the commonly used time signature of 4/4.
Here is a drawing I use in my music classes. I'm sure, it is clear for you.
Time signature determines how many beats within a measure (upper number, numerator) and the value of the beat (lower number, denominator)
So the time signature 5/4 means "there are 5 beats within a measure, and each beat has a value of 1/4". 6/8 means
"6 beats/measure, beat=1/8", and so forth.
In other words, note values are mere fractions, measures are arrays of fractions and time signature determines a size of the array and the time grid.
HTH.
