Introduction to musical notation

Musical notation is used to indicate the pitch (how high or low), temporal information (speed or placement in time) and duration (how long) of discrete sounds, which we call notes. Notes are graphically represented by various signs depending on their duration and position. Notes are named successively using the first seven letters of the Roman alphabet, i.e. A, B, C, D, E, F, G.( however the musical alphabet is C.D.E.F.G.A.B.C.) The notes that continue upwards beyond G begin at the beginning of the sequence with A again. The interval from one A to the next A is called an octave (i.e. : 8 notes). Likewise, the interval between one C and the next C is also called an octave, etc...


Treble Clef Staff



Bass Clef Staff
The notes are placed on a set of five horizontal lines separated by spaces. This group of five horizontal lines is referred to as a staff or stave. The plural form of either word is staves. The position of the note on the stave is directly related to its pitch. Thus, the higher up the stave the note is, the higher its pitch. The notes which fall outside of the range of the staff are placed on, above or below shorter lines, called ledger lines.
 In order for us to be able to determine the exact pitch of any note on the stave, we make use of a symbol called a clef, which is placed at the beginning of each stave and enables us to determine the pitches of the notes for that particular stave.

 There are many different clef signs, the two most common are the Treble (G) clef and the Bass (F) clef. The treble clef is an embellished G, and sits on the second line from the bottom of the stave, making notes placed on that line G's. The bass clef is an embellished F, which looks like a backwards C with two dots on top of each other (like a colon), and the two dots are on either side of the fourth line from the bottom (second line from the top) of the stave. This causes every note on that line to become F's.
