Tuning a horn
Horn parts are written in F, so a written C sounds as the F a fifth below. Set the main tuning slide first. Pull it out to lower the pitch and push it in to raise it.
Your right hand in the bell changes the pitch, so keep it in your normal playing position while you tune. On a double horn, tune the F side and the B♭ side, each with its own slide.
Horn parts are written in F, a fifth above concert pitch (the note that sounds). The tuner shows the note you read, so you can tune straight from your part.
How to use it
Press Start tuning and play your tuning note with your hand in its normal place in the bell. Adjust the main slide until the needle is in the centre.
Frequently asked questions
What key is the French horn in?
Most horn parts are written for horn in F, which means written notes sound a perfect fifth lower. Double horns also have a B♭ side, but you still read the same F parts.
How do I tune a double horn?
Tune the main slide on the F side first, then the B♭ slide with the thumb valve pressed. Check a few notes on each side.
Does my hand position affect tuning?
Yes. Covering more of the bell lowers the pitch. Tune with your hand where it normally sits.
