Hi @Teleblaster. Sorry in advance for the monster comment, I hope it helps.
There certainly is a lot of content like this, and it has become a dogma in musical pedagogy. Unfortunately, it’s totally misinformed and doesn’t reflect reality.
People who advocate this approach are making two critical assumptions which are both very flawed. The first is that you can determine the “correct muscle memory” for fast playing before playing fast. The second is that you can train your nervous system in a simple linear progression.
This just isn’t the case for the fretting hand either. It’s entirely possible that whatever sequence of movements used while fretting slowly will not scale up to faster tempos. I’d argue that it’s more than possible, it’s highly likely. If you’re concerned with things like “economy of motion” or “finger independence,” then I’d argue that it’s almost a certainty.
I’m aware this sounds incredibly dismissive. I’m aware that the idea of slow incremental practice has existed in piano and violin pedagogy for centuries. I’m aware that the position is held by the majority of online guitar instructors. It’s just plain wrong.
If you can accept that, then here’s my next heresy. Most “fast” guitarists (and frankly, violinists and piano players) really aren’t that fast in a nervous sense, but drummers are fast. Actually, stupid ridiculous fast. Try to think and practice like a drummer!
If you can accept all of that, then here’s the process as I understand it.
For both the picking and fretting hand, we habituate positions of low background tension. This will facilitate playing fast without fatigue, but importantly, it also increase our sensititivity to haptic stimuli. That is, we improve the tactile, proprioceptive and kinaesthetic perceptions of our hands.
We organise into positions and movements through our haptic perception, and heightened sensitivity allows us to discover mechanics based upon efficient muscular activation which strongly connect to our internal clocks.
I’ve written some checklists of criteria for both hands that students have foudn helpful.
For the picking hand, we require:
- Efficient muscular activation against low background tension.
- Strong connection to internal clock.
- High dynamic range.
- The capability to reliably escape in at least one direction.
- Tracking capability across all strings.
For the fretting hand, we require:
- Efficient muscular activation against low background tension.
- Strong connection to internal clock.
- Postition and string tracking capability.
- Facilitation of some musically applicable fretboard shape/figure/structure.
- Facilitation of monophony or polyphony (contextual)
- Faciliation of some fretting hand articulations (contextual)
We have to actually test that the mechanics we have are meeting those criteria. However, we organise into positions and movement through our haptic perceptions, and by facilitating those perceptions and having clear criteria to inform our feedback loops, we’re starting strong.
Concurrently, we build a vocabularly of transferrable rhythmic coordinations (or rudiments) which are chunked in connection to our internal clocks. There’s a lot to be said about that process and what makes a coordination amenable to being played fast, but here’s the big picture.
First, we need to memorize the sequence of notes to be played. Slow playing is an effective strategy at this stage. Once this is done, we focus on connecting that coordination to our internal clocks.
We start with movements which are large, powerful and which feel easy. We include strong accents, which test the efficiency of our movements, which lock our movements to our internal clocks and which provide strong haptic markers for synchronisation and chunking. If we ever lose our accents, our sense of time or if things feel strenuous, we stop immediately and start over. We do not stop for accuracy mistakes ever. If you can recover while staying in time, you take the opportunity to train you recovery.
Believe it or not, after several repetitions your motor system is already building “draft” programs of how best to execute this sequence. However, these “drafts” are rough, and are unlikely to be viable at higher tempos. We need to filter out the bad drafts.
So, we trust our internal clocks and we attempt to play the sequence as fast as we can feel it. If our movements are strongly connected to our sense of time, it really is as simple as setting our internal clock to a higher tempo, like a studio master clock.
It will almost certainly fail, but that’s the point. Your draft was bad, and now your motor system gets the message that your draft was bad. You now have clear feedback that the program you were building doesn’t work.
Alternate between the moderately slow but rhythmically clear tempo, and fast attempts. Explore different movement possibilities. Do so for maybe 5 minutes, 10 at the absolute most. Beyond that point, we’re into diminishing returns. Our short term memory is full of “bad drafts,” and we need a refractory period before we can go again.
If we keep creating the conditions, we will inevitably have an attempt which has some potential. You might not fully understand why, but it will feel different. Repeat it several times and let yourself perceive it.
Now, this sensory experience acts backwards to inform your moderate speed repetitions. You start building better drafts, and you start to hone in on what works.
Now, we try to find a transitional tempo where our repetitions begin to experience mistakes, but where we don’t lose our rhythmic connection. We some spend time in this zone to learn to distinguish between a better and worse attempt through feel. Our motor system gets a clear message. If it feels like this, good. If it feels like that, not good.
Then, aim for a tempo again, until something feels new and promising again, and repeat the process.
Don’t get stuck on any one rudiment for too long. Practice a small number of coordinations concurrently, and if one isn’t working, leave it aside for a while and come back to it again in future. Forgetting is actually helpful, it allows you a fresh start in future. Don’t go back to slow incremental repetitions, you’re just reinforcing the bad drafts.
Explore all the different ways your rudiments can be used musically. The only limit here is your imagination.
In time, this vocabulary of movement solutions acts as a basis, which informs all future learning. Your basis becomes a self-reinforcing foundation, and the effects are compounding. Growth is exponential, not linear.
This is how drummers practice, and it works. They know how to connect their movements to their sense of time because percussion is totally concerned with movement and moment.
