| 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 following table lists the standard transposing instrument "keys" (see [[http://en.wikipedia.org/wiki/Transposing_instrument|Wikipedia]] for a full list) together with their corresponding ''I:transpose'' values. Here the enharmonic indicators clarify which alternative is chosen although, since most key signatures don't have enharmonic equivalents, they would be superfluous in most cases. | + | The following table lists the standard transposing instrument "keys" (see [[http://en.wikipedia.org/wiki/Transposing_instrument|Wikipedia]] for a full list) together with their corresponding ''I:transpose'' values.
