Answer:

KEY SIGNATURES

1. No sharp, no flat

2. one sharp

3. six sharps

Explanation:

KEY SIGNATURES are written at the beginning of the staff which can either be in the family of sharp or flat. It tells the corresponding notes that are affected with the sharp or flat.

1. In key of C Major, all the notes of the diatonic scale are not affected by either a sharp or a flat. Therefore for the key signature, no flat or sharp at the beginning of the staff.

2. In the Key of G Major belongs to the sharp family of key signature. The is only one note that is being affected by a sharp and that is the F. In effect, all notes that fall on  the F are all sharp.

3. Key of F# Major has six pitches that are affected by the sharp. In the Key signature, these pitches are the F,C,G,D,A,E. Again all notes in F,C,G,D,A,E are all sharp, they may be within the staff, or are written on the ledger lines/spaces below or above the staff.

For the sequence in the writing of the sharps in the sharp family of key signature, the first sharp is written at the topmost line (F) then go down by four (3rd space, C) and go up by five (1st ledger space above the topmost line, G), then go down again by four (4th line, D), then go down by four (2nd space, A), then go up by five (4th space, E).
