Question

label. \do\ is on the second line.

Explanation:

When "DO" is on the second line of the treble clef staff, this is the F clef (also known as the bass clef, but when centered on the second line, it defines that line as F, which is "DO" in this context). The solfège labels for the lines and spaces from bottom to top are:

1. First line: Mi (A)
2. Second line: Do (F, the reference)
3. Third line: Sol (C)
4. Fourth line: Re (G)
5. Fifth line: La (D)

Spaces (bottom to top):

1. First space: Fa (B)
2. Second space: Ti (E)
3. Third space: Mi (A)
4. Fourth space: Sol (C)

Answer:

Labeled solfège for the treble clef staff (with "DO" on the second line):

• Lines (bottom to top): Mi, Do, Sol, Re, La
• Spaces (bottom to top): Fa, Ti, Mi, Sol
