Perfectly hit Chopin's first note (6,1)

I believe the answer is:

middle c

I'm a little stuck... Click here to teach me more about this clue!

'note' is the definition.
(middle C is a musical note)

I don't understand how the remainder of the clue works.

(Other definitions for middle c that I've seen before include "Tone" , "'Musical note in the centre of the range (6,1)'" , "It's almost at the centre of a piano keyboard" , "Note near piano centre" , "what Jacob has?" .)

I've seen this clue in The Telegraph.
