Answer:
In treble clef, middle C is one ledger line below the staff. C covers the ledger line.
Step-by-step explanation:
On the music staff, there are many places that are the note "C".
Here are some:
In the treble clef
"C" is the third space from the bottom.
Two ledger lines above the staff, C covers the ledger line.
One ledger line below the staff is middle "C", covering the ledger line.
In the bass clef
"C" the second space from the bottom.
One ledger line above the staff with C covering the ledger line, is middle C.
Two ledger lines below the staff is C also, C covering the ledger line.
The two middle C mentioned are the same note, just for different clefs.
