That could be arranged in the extremely unlikely long-term scenario of my music being performed, if ever. Still, it should be noted that my stance towards setting my compositions to actual, real performances has shifted over the last couple of years, which I supposed must be at least part of the reason why Henry Ng Tsz Kiu stopped reviewing my compositions altogether, once I revealed how my position on this matter had changed. Like I said then and I shall repeat now, computerized performances are good enough for my current intents and purposes. If actual performers in the flesh cannot pause to breathe, that poses no problem at all: the machine shall sing or play what they cannot without issue. Naturally, my usual trade-off with this approach is said sense of "artificiality" to it all. But after every time this has been pointed out without me putting the slightiest bit of effort into mitigating such aspects of my music, it should be evident by now I do not mind it whatsoever, it simply does not bother me. However, if this reasoning does clash with your own perspectives, just as I assume happened to Henry, you are free to join him in leaving me and my works alone.
First things first: this is a five-voice motet. The fact that you implied both the supposed melodic "incoherence" of the soprano line and its relatively high range in the very same comment leads me to believe you should be aware of the constraints set by having five voices in a choral setup. Had I chosen to add more variety to the soprano line in particular, I would have found myself trapped between two different dead ends: either substantial voice crossings between the soprano and mezzosoprano voices, or exceeding even the most extreme ranges for soprano voices. As neither of said options were to be permitted, I had to opt for quite a limited range so as to make rooom for the inner voices. Does this somehow make the resulting melody "incoherent"? Like I have said before, what constitutes a good melody is rather subjctive. All I can point towards in my defense is the meticulous care I put into its construction so as to avoid repeated segments (for example, say, a succession of E F E F with very similar rhythms throughout), that is, the only objective metric by which to judge melodic coherence I could apply in this case.
