-There have been a number of people who have queried the need for independent shift operators (''​shift-score''​ and ''​shift-sound''​) and actually they are probably not necessary for standard transposing instruments,​ where all that is required is to specify the transposition between concert pitch and the instrument'​s written pitch.+There have been a number of people who have queried the need for independent shift operators (''​score''​ and ''​sound''​) and actually they are probably not necessary for standard transposing instruments,​ where all that is required is to specify the transposition between concert pitch and the instrument'​s written pitch.
  
 In fact, abc already has independent shift operators provided by the ''​transpose=''​ modifier for ''​K:''​ and ''​V:''​ fields (which only affects the playback) and the semi-official ''​%%transpose''​ directive (which only affects the typeset score). In fact, abc already has independent shift operators provided by the ''​transpose=''​ modifier for ''​K:''​ and ''​V:''​ fields (which only affects the playback) and the semi-official ''​%%transpose''​ directive (which only affects the typeset score).

-However, don't forget that the piper typically has several sets of pipes, and so the ''​shift-sound''​ modifiers will change for each different set of pipes.+However, don't forget that the piper typically has several sets of pipes, and so the ''​sound''​ modifiers will change for each different set of pipes.
  
 ** Conclusion: ** independent shift operations are already in use in abc files and are very much a requirement for an update to the transposition syntax. ** Conclusion: ** independent shift operations are already in use in abc files and are very much a requirement for an update to the transposition syntax.
