I find after 10 minutes, my head really wants to explode practicing the Bach. And practicing Beethoven slowly takes conscious effort.
I learned something really important last year. Don't go past 10 minutes or even 10 minutes with this kind of thing.
A meticulous approach to playing Bach is a very good thing, from the technical, and from the ear.One develops more the ability to hear 'polyphonically' - and in that light,play with more deliberate control.I think playing backwards can be a good idea - which is, with Bach, usually very musical as well - but also mitigates against hand memory - (where the ear can fall asleep) - . This exercise will keep the ear and the reading very alert.Bach is not easy. What you now feel as intense resistance ('head want to explode') is the difficulty of growth.. As you persist with Bach, it does get easier, but can take awhile.. But you are also acquiring new skills that can be applied to All music..Who you now resist may be your best friend in disguise - Bach. The benefits he offers towards musicianship are great - perhaps the greatest.As Beethoven said, (with a play on words), "Bach is not a brook, but an ocean".. True, dat.
?)Also, do you practice each measure repeatedly? Or cycle between/among two-three measures?
work ethic equals inefficient mediocrity.
