Bro unless your teaching piano to URM while at the same time curing cancer I wouldn't confuse them with more stuff that could just distract them from your application, If you didn't get an R till now your doing real well, good luckAlso interested in this - I’d love to send a letter of interest but I have zero material for an update later (same job, same volunteering, not taking classes) unless BU is interested in my very mediocre attempts to re-teach myself the piano.
