| When included in the tune header (or even the file header) the ''I:shift to-sounding'' directive can be used to typeset a complete score (or even all the scores in a file) at //sounding pitch//. To accomplish this it effectively ignores all of the ''shift-score'' modifiers and treats all of the ''shift-sound'' modifiers as if they were ''shift-both''. | When included in the tune header (or even the file header) the ''I:shift to-sounding'' directive can be used to typeset a complete score (or even all the scores in a file) at //sounding pitch//.
