<p>Looking at the schedule at [Spring</a> 2011 Schedule of Classes](<a href=“http://new.oberlin.edu/office/registrar/documents/schedules/2010-2011/spring11schedule.html#anchor1199436]Spring”>http://new.oberlin.edu/office/registrar/documents/schedules/2010-2011/spring11schedule.html#anchor1199436) it appears that there are a number of ensembles that meet exclusively after 4:30, but also some that meet earlier in the afternoon. </p>
<p>The orchestra, chamber orchestra and wind ensemble all meet from 2:40 - 4:30 either two or three days a week. The contemporary music ensemble meets from 12:30 to 2:25 three days a week. Those groups account for most or perhaps all of the required large ensembles that most instrumentalists must take each semester. It is a bit easier for singers because choir, chamber choir, women’s chorale and the collegium musicum all start at 4:30.</p>
<p>It appears that most science labs run from 1:30 to 4:20 one day a week, so it should not be much of a problem for singers, but instrumentalists would need to do a lot of planning and get some co-operation from both the Con and College concerning which ensemble and which section of labs they are assigned to. It could get kind of hairy for instrumentalists who are trying to fit in two lab courses and a large ensemble in the same semester.</p>
