Hello, and welcome to ZarembaMusic Publishing. I’m so delighted you’re here; there are professional studio recordings of most of the charts available here, and the few that don’t are live recordings from various performances and settings. I hope you find what you’re looking for! I’m very fortunate to have most of my music self-published and my arrangements are mostly available at UNC Press and Sheet Music Plus.
The grading system is explained here: 1=Middle School, 2=young high school/advanced middle school 3 = average high school, 4=advanced high school/average college 5 = advanced college/very advanced high school 6 = professional. I’ve seen several high schools pull off grade 6 charts with enough rehearsal. Often it has less to do with readability and how much rehearsal time you have. If you have any questions at all, please drop me a line in the contact section. You can also reach out about commissions and clinics there if you are so interested. Thank you again!
