(7)= Seventh

Mid. C

 Each horizontal line = 1 half-note = 1 fret
 Chromatic Scale = Each half-note is 5.95%
 higher in frequency than the previous note.
 1 octave = 12 half-notes = doubling of frequency

 261.63 Hz. = Middle C
The musical scale is based upon the 12th root of 2.
Each note is 1.05946309 times the frequency of the adjacent lower note.
Note that 110.00 Hz. has been called the "alien frequency", due to the Hypergeum resonance. AKA "Holy Frequency". Yet others say it is 111.00 Hz.
