Return to Tips for Trombone Trombone Tuning	by Dr. Deb Scott Assistant Professor of Music Trombone SFA School of Music dscott@sfasu.edu

Tuning the Main Tuning Slide

• Tune the main tuning slide on all trombones to top of the staff Bb.  The trombone is pitched in concert pitch (Bb=Bb), however it is called trombone in Bb.
  
  
• F-attachments should be tuned to fourth line F, thus allowing the bottom of the staff F (an octave lower) to be in tune in first position.
  
  
• Bass trombonists should tune their main tuning slide and their F attachments as above.  The D or Eb attachment should be tuned to the middle of the staff D or Eb in first position respectively.

Slide Positions

• The trombone can play perfectly in tune or atrociously out of tune depending on the knowledge and attention given to slide positions.
  
  
• First position -- Slide fully in, lightly touching the corks or springs.
  
  
• Second position -- About an inch and a half of the inner slide showing.
  
  
• Third position -- Brace even with or slightly above the end of the bell.
  
  
• Fourth position -- Top of outer slide even with or slightly below the end of the bell.
  
  
• Fifth position -- (no man's land) about half-way between fifth and sixth positions.
  
  
• Sixth position -- About an inch above the stockings (the line at the end of the outer slide) or a comfortable arm's length.
  
  
• Seventh position -- About an inch and a half past the stockings.  his is as far as most people can reach.
  
  
• For short arms: Use tips of two fingers releasing thumb from brace to reach seventh.  Move right shoulder in.  Extremely short arms may need to tie a string from finger to brace and "throw" the slide.
  
  
• All positions should be checked with a tuner frequently, especially f# in 5th, low c in 6th, and low b in 7th.  Remember that young students will be growing (and so will their arms.) 
  
  
• There is no substitute for a good ear. Hearing intonation problems can be taught. It is important to remind students to listen to what they are playing.
