Reading Clefs

### Core Idea

Pitch in Western musical notation is designated by the letters A, B, C, D, E, F, and G, which repeat in a loop. Different clefs make reading different ranges easier.

### Explanation

Pitch in Western musical notation is designated by the letters A, B, C, D, E, F, and G, which repeat in a loop.

Different clefs make reading different ranges easier.

Each clef indicates how the lines and spaces of the staff correspond to pitch.

In Western musical notation, pitches are designated by the first seven letters of the Latin alphabet: A, B, C, D, E, F, and G. After G these letter names repeat in a loop: A, B, C, D, E, F, G, A, B, C, D, E, F, G, A, B, C, etc. This loop of letter names exists because musicians and music theorists today accept what is called octave equivalence, or the assumption that pitches separated by an octave should have the same letter name. More information about this concept can be found in the next chapter, The Keyboard and the Grand Staff.

This assumption varies with milieu. For example, some ancient Greek music theorists did not accept octave equivalence. These theorists used more than seven letters of the Greek alphabet to name pitches.

Clefs and Ranges

The Notation of Notes, Clefs, and Ledger Lines chapter introduced four clefs: treble, bass, alto, and tenor. A clef indicates which pitches are assigned to the lines and spaces on a staff. In the next chapter, The Keyboard and the Grand Staff, we will see that having multiple clefs makes reading different ranges easier. The treble clef is typically used for higher voices and instruments, such as a flute, violin, trumpet, or soprano voice. The bass clef is usually utilized for lower voices and instruments, such as a bassoon, cello, trombone, or bass voice. The alto clef is primarily used for the viola, a mid-ranged instrument, while the tenor clef is sometimes employed in cello, bassoon, and trombone music (although the principal clef used for these instruments is the bass clef).

Each clef indicates how the lines and spaces of the staff correspond to pitch. Memorizing the patterns for each clef will help you read music written for different voices and instruments.

Reading Treble Clef

The treble clef is one of the most commonly used clefs today. Example 1 shows the letter names used for the lines of a staff when a treble clef is employed. One mnemonic device that may help you remember this order of letter names is "Every Good Bird Does Fly" (E, G, B, D, F). As seen in Example 1, the treble clef wraps around the G line (the second line from the bottom). For this reason, it is sometimes called the "G clef."

Example 1. The letter names for the lines with a treble clef.

Example 2 shows the letter names used for the spaces of a staff with a treble clef. Remembering that these letter names spell the word "face" may make identifying these spaces easier.

Example 2. The letter names for the spaces with a treble clef.

Reading Bass Clef

The other most commonly used clef today is the bass clef. Example 3 shows the letter names used for the lines of a staff when a bass clef is employed. A mnemonic device for this order of letter names is “Good Bikes Don’t Fall Apart” (G, B, D, F, A). The bass clef is sometimes called the “F clef”; as seen in Example 3, the dot of the bass clef begins on the F line (the second line from the top).

Example 3. The letter names for the lines with a bass clef.

Example 4 shows the letter names used for the spaces of a staff with a bass clef. The mnemonic device "All Cows Eat Grass" (A, C, E, G) may make identifying these spaces easier.

Reading Alto Clef

Example 5 shows the letter names used for the lines of the staff with the alto clef, which is less commonly used today. The mnemonic device “Fat Alley Cats Eat Garbage” (F, A, C, E, G) may help you remember this order of letter names. As seen in Example 5, the center of the alto clef is indented around the C line (the middle line). For this reason it is sometimes called a "C clef."

Example 5. The letter names for the lines with an alto clef.

Example 6 shows the letter names used for the spaces of a staff with an alto clef, which can be remembered with the mnemonic device “Grand Boats Drift Flamboyantly” (G, B, D, F).

Example 6. The letter names for the spaces with an alto clef.

Reading Tenor Clef

The tenor clef, another less commonly used clef, is also sometimes called a “C clef,” but the center of the clef is indented around the second line from the top. Example 7 shows the letter names used for the lines of a staff when a tenor clef is employed, which can be remembered with the mnemonic device “Dodges, Fords, and Chevrolets Everywhere” (D, F, A, C, E):

Example 7. The letter names for the lines with a tenor clef.

Example 8 shows the letter names used for the spaces of a staff with a tenor clef. The mnemonic device "Elvis's Guitar Broke Down" (E, G, B, D) may make identifying these spaces easier.

Example 8. The letter names for the spaces with a tenor clef.

Ledger Lines

When notes are too high or low to be written on a staff, small lines are drawn to extend the staff. You may recall from the previous chapter that these extra lines are called ledger lines. Ledger lines can be used to extend a staff with any clef. Example 9 shows ledger lines above a staff with a treble clef:

Example 9. Ledger lines extend a staff upwards with a treble clef.

Notice that each space and line above the staff gets a letter name with ledger lines, as if the staff were simply continuing upwards. The same is true for ledger lines below a staff, as shown in Example 10:

Example 10. Ledger lines extend a staff downwards with a bass clef.

Notice that each space and line below the staff gets a letter name with ledger lines, as if the staff were simply continuing downwards.
