This is a book of arrangements, not transcriptions. Modifications have been made in voice leading (as slight as possible), key (in some cases), and register. Additionally, small liberties have been taken with dynamics, phrasing, and rhythm. In the case of the Brahms Canons, many originally had no tempo markings, no phrasing, and few dynamic indications (in some cases, there were no dynamics at all). I have gone through these pieces and added most of the dynamics, phrasings, and metronome marks present. I have added to Brahms' markings and removed none. As this is not intended to be an academic score, none of these alterations have been indicated or differentiated from the composers' markings.
