Resources for Students
This short list is not comprehensive but rather is meant to help you get started....

The best of the best:

International Horn Society  
This site is perhaps the best resource for all things horn, including lists of everything you need as a horn player and up to date information on upcoming horn events.

IMSLP Petrucci Music Library 
This site is dedicated to sharing music currently available in the public domain, which is A LOT, and you can view, download and print tons of great pieces!

YouTube
Search for Horn Solo, and look for clips that look professional. If you are just getting started on horn, I suggest you start with Mozart and Strauss.

Other Great Resources

Fingering Chart or Fingering Chart 
Both of these charts provide fingerings for the double horn.

Blank Sheet Music
Design and print your own staff paper! You choose clef, time and key signature, then print. Great for writing your own cadenza or exercises.

Metronome Online  
If you want to use your computer as a free metronome, bookmark this accessible and free online metronome for your practice sessions!  

Musical Glossary For Kids
A big thank you to Ms. Annie P. and all her students, especially Jessica! They have found this resource page useful, and kindly suggested I add this great resource for musical terms! :)

Metronome & Tuner: Online, App or Physical?
A tuner and metronome are essential. I like the Korg CA-30 and Dr. Boss products but there are online tuners and metronomes and great apps such as Tonal Energy and Cleartune.
