    <para id="p1a">The first symbol that appears at the beginning of every music <cnxn document="m10880" strength="9">staff</cnxn> is a <term>clef symbol</term>. It is very important because it tells you which <cnxn document="m10945">note</cnxn> (A, B, C, D, E, F, or G) is found on each line or space. For example, a <term>treble clef</term> symbol tells you that the second line from the bottom (the line that the symbol curls around) is "G".  On any staff, the notes are always arranged so that the next letter is always on the next higher line or space. The last note letter, G, is always followed by another A.

		<name>Memorizing the Notes in Bass and Treble Clef</name>

One of the first steps in learning to read music in a particular clef is memorizing where the notes are. Many students prefer to memorize the notes and spaces separately. Here are some of the most popular mnemonics used.

    <name>Moveable Clefs</name>

    <para id="p2a">Most music these days is written in either bass clef or treble clef, but some music is written in a <term>C clef</term>. The C clef is moveable: whatever line it centers on is a <cnxn document="m10862" target="p2bb">middle C</cnxn>.

    <para id="p2b">
The bass and treble clefs were also once moveable, but it is now very rare to see them anywhere but in their standard positions. If you do see a treble or bass clef symbol in an unusual place, remember: treble clef is a <term>G clef</term>; its spiral curls around a G. Bass clef is an <term>F clef</term>; its two dots center around an F.

    <para id="p2c">
Much more common is the use of a treble clef that is meant to be read one octave below the written pitch. Since many people are uncomfortable reading bass clef, someone writing music that is meant to sound in the region of the bass clef may decide to write it in the treble clef so that it is easy to read. A very small "8" at the bottom of the treble clef symbol means that the notes should sound one octave lower than they are written.

    <para id="p3a">

		<caption>These scores show the same notes written in treble and in bass clef. The staff with fewer ledger lines is easier to read and write.</caption></figure>

    <para id="p3b">The G indicated by the treble clef is the G above <cnxn document="m10862" target="p2bb">middle C</cnxn>, while the F indicated by the bass clef is the F below middle C. (C clef indicates middle C.) So treble clef and bass clef together cover many of the notes that are in the <cnxn document="m12381" strength="8">range</cnxn> of human voices and of most instruments. Voices and instruments with higher ranges usually learn to read treble clef, while voices and instruments with lower ranges usually learn to read bass clef. Instruments with ranges that do not fall comfortably into either bass or treble clef may use a C clef or may be <cnxn document="m10672" strength="5">transposing instruments</cnxn>.
