 This page contains the eighth draft of a proposal to extend the transcription capabilities within abc (following hundreds of messages on the abcusers mailing list in Sep 2011 and subsequently in Dec 2011 - Feb 2012). It is based on numerous comments, suggestions and proposals from lots of contributors. This page contains the eighth draft of a proposal to extend the transcription capabilities within abc (following hundreds of messages on the abcusers mailing list in Sep 2011 and subsequently in Dec 2011 - Feb 2012).

-The eighth draft is a minor change from the seventh and fixes problems with enharmonic alternatives that arose due to the adoption of pragmatic enharmonic indicators (which contradict the tonal enharmonics needed by transposing instruments ​in a few cases). The only sections affected are [[#​enharmonic alternatives for transposing instruments]],​ [[#​enharmonic alternatives for transposition]] and the [[#​instrument transposition table]].+The eighth draft is a minor change from the seventh and fixes problems with enharmonic alternatives that arose due to the adoption of pragmatic enharmonic indicators (which, in a few cases, ​contradict the tonal enharmonics needed by transposing instruments).

 The seventh draft is a minor change from the sixth and just modifies the way ''​I:​transpose''​ instructions interact with each other (they override rather than combine).
