In close harmony voicings with section soli, i.e. 5 saxes in close harmony, what rulings apply, if any? From the early US big bands - 1930 onwards through each era of swing, be-bop, modern, contemporary.
These half-tone voicings between the top two instruments can upset the ear in some instances, when the inner voicing suddenly shoots out audilby, seeming to unbalance the rest of the lateral harmonic movement. (The piano is different of course, and doesn`t apply).
Of course the tempo of the music can hide or display even wrong notes to some degree, but I`ve no wish to suggest that writing half tones can be right or wrong. .
