Day 3 - Measures and Time Signatures

Bar lines divide the staff into measures; measures are segments of musical notation denoting the notes according to the time signature.

Time signatures: amount and types of notes in a measure. If you have two measures containing time signatures in 4/4 and 3/4 time, that means each time signature contains a certain number of quarter notes - 4 and 3 quarter notes respectively; a 4/4 time signature therefore contains two half-notes (or a whole note) and a 3/4 time signature contains 3 quarter notes, or a half and quarter note. Non quarter note time signatures can include 6/8 and 3/2 - 6/8 equals six eight notes and 3/2 equals three half notes, or 6/8 equals a half and quarter note and 3/2 equals a whole and half note.
