Programming for Orchestra
There are SO MANY pieces you can choose from and, depending on where you're looking, ​grade levels are not always a reliable indicator of difficulty.
Different publishers use different methods, and even the Florida Orchestra Association speaks in both number-based "grade levels" as well as letter-based orchestra classifications (most applicable during MPA season).

So what should you look for when programming for your orchestra?

The most common mistake new-to-strings teachers make in programming is forgetting to consider the technical demands of the pieces they choose. Of course, the pieces need to be musically worthwhile and engaging, which can be evaluated based on listening and looking at rhythmic demands. HOWEVER, the string technique required to play some of these pieces may be much more demanding than it would initially appear.

Read below for some technique items to look out for.
Repertoire
Below you will find descriptions and music lists for each of the 5 classification levels of orchestras in FOA. Each section will have two buttons specific for that level.

The first button opens the MPA list provided by FOA. The FOA lists are updated annually through the FOA website. The lists on this page are current as of 2017.  For a more updated list, please visit  http://myfoa.org/mpamusic.

The other button you'll see brings you to a resource created in 2012 by Lisa Hopko and Michael Simpson of Orange County Public Schools in Central Florida. Together they compiled a list of suggested standard repertoire for the orchestra programs in OCPS.

These lists are by no means exhaustive--there are tons of wonderful pieces for orchestras and many great new works published each year. Music reading sessions at conferences often give directors the opportunity to experience and discover these new pieces for themselves. However, as you're trying to get a few pieces together to get started with, I hope these documents can provide a bit of guidance.

But first... Terminology
Jargon... isn't it great? Here are some terms used on this page that may need defining if you're from out of town.

FOA 
Florida Orchestra Association
MPA 
Music Performance Assessment (sometimes called "Festival")
OCPS 
Orange County Public Schools, FL

The "S" in AS, BS, CS, DS, and ES 
S stands for String Orchestra
The "F" in AF, BF, CF, and DF 
F stands for Full Orchestra
A, B, C, D, and E 
Indicate level of difficulty - A is harder than E

ES - Grade 1
Suitable for late first year to second year players, on average. Characterized by first position, simple rhythms, and basic forms. Caution: some mature music is hidden in ES music due to "simple rhythms," but actually requires demanding string techniques. Watch out for these mis-graded pieces. They may be excellent selections for your more proficient players!
