TIPS for making INSTRUMENTAL MUSIC RÉSUMÉS
Résumés highlighting your instrumental music work are different from your typical business résumé.
Check out THIS GUIDE created by the Eastman School of Music. It outlines all of the information you should include on a solid musician's résumé.
All credits should be listed in REVERSE CHRONOLOGICAL ORDER - the most recent roles/work should be listed at the top and then work backwards. Think of it this way: If someone is going to skim your résumé, you want that person to know about your most recent work FIRST.
