ABSTRACT
There are Bass, Tenor, Alto, and Treble different clefs because voices and many instruments perform in a relatively limited range. When notated in the Treble clef, however, an unwieldy number of ledger lines are required, making the melody rather difficult to read. When the same melody is notated an octave higher, the Alto and Treble clefs become more reasonable choices. Stepwise melodies are typically easy to write down because it is easy to follow the contour of the melody, which is why the first two modules only include melodies that move by step. Because all the other intervals in the scale are whole-steps, these half-steps give the major scale its characteristic sound. When the same melody is notated an octave higher, the Alto and Treble clefs become more reasonable choices. The staves were left blank on purpose.
