Man. That is some complicated jargon. I'm going to have to read this when my mind is more awake haha!

I'll throw my hat in with Ramon! I couldn't make it through this gobbledygook(no offense intended to D. Norton) without thinking about the blatantly perverse concept of teaching music in the Y2K. What the hell are we making??? Robots??? Music boxes??? Electrokinetic Music Mannequins? What does this have to do with the functional and artistic seasoning of a musician? I have been crying this song for years that we are losing the human element of making music and musicians. Musical instruments were made by Man to duplicate the feeling, emotion, and beauty of the human voice and song. When you play an instrument it should sing like a human voice: breathe, pause, stop, start, emote, become loud, soft, frenzied, sad, happy . . . and when you teach prospective musicians you must make them understand this concept since if you just play the notes you're not playing music. Dull musicians are dull people. You cannot create Art if you've lived your life like a careful accountant where every aspect of life is measured and calculated. How can you truly feel and understand what a composer means when he labels a piece of music "Lagrima"--the tear, "Pathetique," "Lob der Thranen"-- in praise of tears or "Liebesbothschaft"--message of love? If you have no experience in life and haven't pushed it to the limit, your music will reflect your life. An artist is like a fine wine . . . it must be made with good grapes and it must have spent the necessary time in the bottle to create an excellent wine. Anything else is mouthwash. Playing again . . . Rognvald

I personally dislike using the single gesture/compound [single] stroke terminology because I see it as potentially confusing matters. What that is referring to is conscious versus subconscious control; however when we execute a series of movements subconsciously they are still individual (i.e. not synchronous but separated in time) movements, just not individual conscious movements.
Yes, the distinction exists at the level of unconscious initiation of the motor program, and at the level of conscious command, but not usually at the level of the muscles. We live at the level of conscious command, so I still think there is a place for it - we just have to remember that at some point in the chain, it is broken down into individual tasks.
I think where we differ is when you say "not usually at the level of the muscles". The motor program is still a series of separate commands driving separate muscles or muscle bundles in some memorized and internalized sequence; hence I don't like it being called a single gesture or stroke. As an easy example, consider fast i-m alternation at tempo 150x4 or faster. Even if you are convinced that the flexor muscle activation is the same command for both i and m (I don't since we have individual control over these fingers, but let's skip over that), there is an alternation of flexor, extensor, flexor, extensor for each i-m-i-m set, done subconsciously at that speed. ("Passive return" is not fast enough to accomplish the finger reset for its next stroke at that speed). Or perhaps I've misinterpreted your view on this.
What I meant is that it may often make sense to draw a distinction between single commands and bundled commands at the level of unconscious initiation of the movement, and at the level of the perceived command, but it will only rarely make sense at the level of the individual muscles, because the command is almost always individualised by that point. I agree that in the case of im alternation, there are individual commands arriving at the muscles controlling i and m. I think that must be so even if the flexor is shared, because that would mean that flexing i by itself involves contracting the shared flexor while simultaneously contracting an extensor that acts on m but not i. The exception I had in mind (I wrote ma when I should have written am) was where you flex a and m comes along for the ride. In that case you have one muscular contraction bringing about two strokes, and in that sense there is bundling even at the muscular level.

A motor program has to consist of individual commands, I agree – but to call it a program is not to deny that so much as to suggest that, for the purpose at hand, it is more useful to look at it as one bundle. I suspect we agree on that and your point is that once we get down to the level of the muscles, it is no longer useful to look at them as a bundle. That is exactly what I was trying to say though.

I am starting to think that the idea of bundling is quite useful. I’m not sure I really follow Berg’s logic when he relates it to feedback time, because I can’t see how bundling instructions reduces feedback time. It does make sense though if you assume that HQ (wherever we consider that to be) can only give so many commands per unit of time, but that its minions can handle a lot more. If HQ’s instructions are to carry out pre-prepared bundles of commands, rather than individual ones, it can get more commands executed in the same time. This suggests that we need to spend practice time making up our bundles (I guess through slow/fast practice). I have a hunch that we are better off putting tricky bits in the middle of a bundle, but I haven’t rationalised that yet. I am well into the realm of speculation here, but then so is Berg, and his version doesn’t even seem to make sense.
