I know what notes are in the key of Bb, but if I've been playing C major all day and switch to Bb, it can be difficult to "break out" of C, even though I know the difference intellectually. This can lead to frustration. It sounds like scales can speed up the process, so I will take the advice.
I recently decided to remedy this weakness in my own playing. I'm going through different figurations in each key, so for example I will work in Gm for a few weeks doing harmonic, melodic scales, chords, and arpeggios. What I found worse than going from scale to scale was when I would switch from practicing arpeggios to the scale... My mind wanted to play the scale, but the hands would automatically make motions for arpeggios and it would take a while to adapt.
What's been working for me is to aim my practice for consistancy, the first goal is being able to consistantly pull off a given figuration off the bat (without having to sit down and adapt the hands to it for an hour), when I can do that then I work on being able to consistantly switch between different figurations off the bat. I've been finding that once I can comfortably do a scale with consistancy, it's not so difficult to add speed.
This has been a little breakthrough for me, what I found I'm developing in working on consistancy and freedom (to switch between scales, arps, chords, whatever) is not so much physical dexterity - it seems I've had that all along... But I've been developing in how I
think when playing, and confidence in my ability to pull it off, which is more important than I previously thought. Not to mention enforcing good practice habits.
That being said, should I practice scales at my own pace, experimenting with positions, dynamics, speed, and color, or has there been written a repetoire that might prove useful across pieces and periods? Or am I just thinking too much?
For the repertoire vs exercises debate, my teacher made a good point one day that skillwise it doesn't really matter - you can develop either way. So I like to be practical, in my case I don't always have a lot of time/opprotunities to perform, and I don't like learning repertoire only to forget it later, so I devote more time to forgettable exercises to develop my skill.
For practicing scales and other arbstracted figurations, I believe it's best to follow the principle of always building upon what you can already do. The possibilites are infinite. Just as an example, this is my framework plan of progression with technical exercises:
- learn how to play a scale in a key at a given tempo, then chords (tonic, dominant 7th), then arpeggios (tonic, dominant 7th).
- attain consistancy, being able to play each figurations 2X, 3X, 4X in a row accurately. This is more of a mental endurance exercise than anything.
- attain freedom in switching between figurations in that key.
- do this for all keys, then attain freedom in switching between keys & figurations. Cycling chromatically and around the circle of 5ths. To be able to play any scale/chord/arpeggio on command.
From this kind of foundation I think it would be possible to expand into different figurations (C,E,D,F,E,G... type of things), sequencing in ascending/descending 3rds & 5ths in any given key... Whatever the imagination could come up with. I'm thinking at some point practice on scales would become more and more like free improvisation, and the benefit for repertoire is obvious.
That's an example of the logical extention of the principle of building upon what you can already do, it excites me to think of how these technical exercises can lead to musical freedom. Maybe I'm being unrealistic, but I'm willing to find out. What do you think?
