2C " 2G fifth above.
" 2G " 1G octave below.
" 1G " 2D fifth above.
" 2D " 2A fifth above.
" 2A " 1A octave below.
" 1A " 2E fifth above.
" 2E " 2B fifth above.
" 2B " 1B octave below.
" 1B " 2F[#] fifth above.
" 2F[#] " 1F[#] octave below.
" 1F[#] " 2C[#] fifth above.
" 2C[#] " 2G[#] fifth above.
" 2G[#] " 1G[#] octave below.

By 2C tune 1F fifth below. Temper sharp.
" 1F " 2F octave above.
" 2F " 1B[b] fifth below. Temper sharp.
" 1B[b] " 2B[b] octave above.
" 2B[b] " 2E[b] fifth below. Temper sharp.

Now by 2E[b] try 1A[b] (G[#]) fifth below for the "wolf."

Note that this last trial brings you back to the last tone tuned
before the break.

This system is used by a great number of very successful tuners, and
it has but one appreciable disadvantage, which is that involved in
changing from fifths upward to fifths downward. This difficulty is
easily overcome, if it were all there is to encounter; but in
practice, we find that after tuning the intervals in the above
succession down to the last step in the first series, middle C will
often have changed pitch somewhat, and the last five tones with their
octaves tuned from it will not be in true harmony with the intervals
tuned in the first series. For this reason it is better to go on
through, as in our system, tuning by fifths upward, and if there is
any change of pitch in the first tones tuned, they may be more easily
corrected by going over them in the same way as at the start; also,
the amount of difficulty in locating discrepancies is greatly
lessened.

SYSTEM C.

The following system is one that is followed by many good tuners of
the present day and has many advantages. To use this system
successfully, however, one must be familiar with the number of beats
necessary in each interval used.

Take 1F as a standard.

By 1F, tune 2C, fifth above.
By 1F, tune 1B[b], fourth above.
By 1F, tune 1A, major third above.
By 1F, tune 2D, sixth above.
By 1F, tune 1A[b], minor third above.
By 1F, tune 2F, octave above.
By 2C or 2D, tune 1G, fourth or fifth below.
By 1G, 1A or 2C, tune 2E, sixth, fifth or third above.
By 1G or 2E, tune 1B, third above or fourth below.
By 1A or A[#], tune 2C[#], major or minor third ab
