Translating American Resume to Muvac
I appreciate that on Muvac they want your resume much more shrunk down no b.s. decades long CV. However it’s clear a lot of the labels for experience in the drop down menu are translated from other countries and I want to know what’s acceptable to put in my resume:
-School Ensembles: Paid ones associated with my school I label as “temporary” (idk if this is right) but do I use the “Youth Orchestra” section for unpaid school ensembles or just not include them at all? Normally I wouldn’t include school ensembles but deleting my other gig experience based in chamber music for a Muvac-ok resume is leaving me with room to mention these ensembles
-I imagine being in a sub-list but never performing with an orchestra due to other gigs shouldn’t be listed, but if that’s not the case let me know
-Is the “academy” drop down labels for…

You are correct, functionally it should be viewed as not having made it out of prelims.
Typical US auditions will follow this format:
1) Resume/Application submission
1.5) Prescreening Recording submission
2) Preliminary Round
3) Semifinal Round
4) Final Round
5) Superfinal Round
At the conclusion of the audition there are several possible results: one or more candidates will be offered a position in the orchestra outright; they may be offered a trial, which means they’ll come play with the orchestra for one or more weeks before a hiring decision is made; or nobody will be offered a position nor a trial, resulting in a “no hire”, after which the orchestra will hold the audition again in the future.
That said, there are a few small differences in some procedures, usually based on orchestras’ schedules or specific needs for a particular audition.
For example, most orchestras will not require a prescreening submission, and will invite most (if not all) candidates who submitted an application. Some orchestras, due to having a massive pool of candidates, opt to make their prelims a recorded round, after which they invite candidates to a live semifinal round. Other orchestras will skip the semifinal round altogether, and candidates who advance from prelims go straight to finals. Having a superfinal round used to be rarer, but seems to be a more common practice nowadays.
I will also add, for most orchestral resumes, the committee is looking for a very general “Does this person have experience with a professional ensemble: Yes/No”. With more and more auditions being fully screened, your education, who you’ve played for, competition results, etc. don’t matter nearly as much as how you sound in the audition and subsequently how well you work with and get along with your colleagues.
