The bass clef is easy...just follow the bouncing fish...! 😉
(NOTE: I used the nice images from the article at https://en.m.wikipedia.org/wiki/Clef)
Bass and Treble clefs
Seriously, the bass clef is fine and continues the march downwards set by the G-clef many people know. Middle C is right ON the only ledger line (a little notational aid for notes above or below a staff) which falls between them.
So the E at the bottom of the treble/"G"- clef has the space next to it as D, a ledger line next to that as middle C...
Then THAT "middle C on a ledger line" is the first ledger line ABOVE the bass clef. The space right on top of the bass clef is the B next to middle C, then the top line of that clef is A...
Same ordering sequence.
Note that the bass clef has 2 dots; these are on either side of the F-line in that clef:
This clef sign can actually be placed on ANY of the 5 lines of a staff, but whichever line has the 2 dots on either side of ut, THAT line indicates the F just below middle C ("F3", in the third full octave, counting the C's from left-to-right on a piano; middle C is C4, the beginning of the 4th complete octave).
That also works with the treble clef:
Wherever it is placed, the inner part curls around the line which indicates the G just above middle C ("G4").
C clefs
With the cello, you might have occasion to use one of the C-clefs. Just like the F-clefs (the bass clef being one example) and the G-clefs (including your old pal, treble), the C-clefs always indicate a C (middle C, or C4), but this time it's with the center of a weird shape; you'll likely see this one
That shape always is centered on middle-C, but can be anywhere.
