Also, since I'm not teaching one person individually, it's hard to account for everyone who'll be reading this. One person will probably wonder why I even bother saying some of the things I do, while others will be confused and not understand. Rhythm is particularly difficult to learn just by reading something. You have to actually do it to understand. Even so, I hope this will help a bit, and for those who do understand, the next more advanced lessons will be more of a benefit.
Notes have values.
These values are all relative to other notes. A single note won't be held for a 'certain' amount of time, instead it will be held for an amount of time that corresponds to how long the other notes should be held. For example, a quarter note will be held half as long as a half note. Note values come in powers of 2. The first note is a whole note, and then comes the half note, quarter note, eighth note, sixteenth note and so on.
