Which term is primarily associated with viola and trombone notation to avoid ledger lines?

• A. Treble clef
• B. Bar line
• C. Alto clef
• D. Bass clef

Answer: (C)

Clef choice determines where middle C sits on the staff, which affects how many ledger lines you see. The alto clef, a C clef placed on the third line, centers the viola’s typical range on the staff so many notes fall on staff lines and spaces rather than above or below it. This minimizes or eliminates ledger lines, making the music easier to read for viola players. While trombone parts are commonly written in bass clef (and occasionally in treble for higher passages), the association most strongly linked with avoiding ledger lines for the viola is the alto clef. That’s why this term is the best fit.
