Re: Ottava clef request

I remember seeing these. The pieces are decently well known. In one sense they could be thought of as stylistic alternates of 8va/8vb/15ma/15mb etc. but their placements are very different (and don’t allow an extension spanner or repetition each line). I think of them as clef8va alternates but again they can be used without a clef and they are invariant for whatever clef they are attached to. Maybe they are their own thing? I can’t think of a single SMuFL musical symbol that they have an exact semantic equivalent to. They might be stylistic variants of clefs and also stylistic variants of Ottava signs also.

Usage is probably about equal to some of the middling common microtonal accidentals already accepted.

Best,
Michael

I am requesting an alternative version of the ottava clefs that is used by some composers, beginning with Kaikhosru Shapurji Sorabji. Instead of an 8 above a treble clef, for example, it is followed by Î (the Roman numeral 1 with an upwards-pointing caret, to indicate up one octave). For two octaves, it's ÎI, and for down an octave the caret is at the bottom and pointing downwards. (The same can be done for two octaves, but I don't know if Sorabji ever used that)
Here are examples:

Note that the way that the Î transpositions can be added in the middle of the line might not be the easiest to add, and I think just making new alternative 8va symbols of the clef attached to the Î is fine.
