When we started working on automatic feedback then pretty soon we had to start answering questions about the difference of some qualities of a sound. For example, when we talk about evaluating one’s timing then are we talking about rhythm, tempo or meter? All very different aspects. So what are they?
If there is a dot next to the note, it will add 50% to its duration. For instance, a dotted quarter note would be the length of a quarter plus an eighth.
In time signature, the more important number is the upper one – it shows how many beats there are in a bar. Time signature C means 4/4. This is an ancient time signature, abbreviation from common time, and it is indeed the most common time signature.
One important feature of the MatchMySound automatic feedback algorithm is that in addition to assessing pitch it listens to the timing of the player and indicates where things go wrong (or, let’s not say ‘wrong’ but ‘different’)
