=**Tuning the Double Horn**=
 * 1) Finding the main tuning slide, the F tuning slide, and the B-Flat tuning slide. When the sound is affected by removing a slide, you know that slide is paired with whatever side of the horn you are playing on. For example, you are playing C on the Bflat side of the horn. When you remove a slide from the instrument and attempt to play this C, tone and pitch are affected dramatically. This is a Bflat tuning slide (unless both sides of the horn are affected by removing the slide, in which case it is the main tuning slide.)
 * 2) Tune the open pitches of the Bflat horn by playing third space C (with thumb valve depressed) and comparing to a pitch standard. Adjust the main tuning slide (do all tuning with hand properly in bell).
 * 3) Tune the open pitches of the F horn by playing third space C (without thumb depressed) by comparing to the same pitch on the Bflat side. Adjust the F tuning slide (normally one F slide is used only to empty water; it is then returned to an all-the-way-in position.) (Use the slide farthest from the trigger to tune)
 * 4) Tuning the individual valves on the F and Bflat horns (F side valve slides are longer than those on the Bflat side). Compare notes fingered with individual valves to a tuner or to already in-tune open pitches. Mark the amount with a pencil. Examples;
 * 5) First valve F (first space); T&1 B flat (third space)
 * 6) Second valve B (third space) – on both sides of instrument
 * 7) Third valve A (if used as an alternative for 12)
 * 8) Tune the valve combinations (12,13,123 – the latter two are seldom used)
 * 9) Keep the following relationships between the valves: First valve – twice as much pull as second valve; third valve – three times as much pull as second valve
 * 10) Compromise between amount of pull for individual valve slides and amount of pull for the valve combinations (split the difference using pencil marks as guides; implies lipping will be necessary).
