I'm doing a book in which sixteenth notes are introduced with counts, and I'm wondering when it's appropriate to use note grouping. The measures with counting can have weird spacing; is it unclear to use note grouping then? And if I don't group in those measures, is it confusing to use grouping in other measures of the same piece?
I don't think the grouping will make things unclear, especially with the counting below, which theoretically should help with the understanding of the grouping and counting process.
The braille reader will encounter grouped 16ths and ungrouped 16ths in every piece of music they will learn, so I don't think it's a bad idea to use the grouping as prescribed by the code in early things like this.
