Each week, the choir members receive notes on Thursday from the previous Tuesday rehearsal. The notes include very specific spots in each composition (e.g. measure 14 and the third beat of the alto part, make sure to put the "T" at the beginning of beat 4). We share the general notes that are the prelude to a much longer memorandum. The rehearsal notes come from David Cherwien, artistic director of the National Lutheran Choir, and then are passed on to the section leaders (soprano, alto, tenor, bass) who add their own marginalia.
