It's a good question. Your LH needs to build up a repertoire. Similar idea when learning 5th Species Florid Counterpoint. Having 5th species as your introductory counterpoint studies would be incredibly intimidating. You learn species 1 through 4 then combine them in the 5th species. What you need to do is break down the accompaniment into smaller elements and practice them in isolation. To take the first few measures Op 62/1 as an example, improvise short pieces using only one of these at a time, and try to stick to the pattern:- ascending arpeggios, root as bass note on downbeat- ascending arpeggios, inversions as bass note on downbeat- alternating between two notes, same harmony (eg: B and D#)- alternating between two notes, similar motion (eg: thirds using B major scale)- alternating between two notes, oblique motion (one note stays, the other moves)- ascending arpeggios, bass note root starts on off beat- ascending arpeggios, bass note inversion starts on off beat- LH in counterpoint with RH melody (counterpoint priority over homophonic texture)- LH single bass note downbeat, plus a few notes in counterpoint with RH- LH in counterpoint with RH while holding notes that belong to harmonyAfter you are comfortable doing one, try combining two patterns, then three, and so on.Think of it as the harmony taking lead, while the patterns fall in place. A lot of Brahms' keyboard music does this. Have a look at the late piano works. You could take a hymn and try to stylize it like Chopin or Scribin. The melody, harmony and voice leading are already set out in an orderly manner. It is up to you to arpeggiate the LH and ornament the RH. If you are up to it, try the same with a Bach chorale.Free LH accompaniment will come in time, but you have to work at it.
When I'm improvising a theme I can only hear/think of left hand if the patterns are simple enough, like arperggios or w/e. But when I try being a little more complicated, "free form" on my left hand my brain just short circuits. Idk a classical example of 'free form' would be the first page of Chopin's nocturne op 62 no. 1, sometimes it's arperggios, sometimes its in strict rhythm or sometimes it's syncopated. I mean how do you get to improvise with a left hand as sexy as that? Better examples are also found in Scriabin's music. You guys know what I'm talking about right?Now I could settle for "okay I'm just not talented" but even the world class Jaz pianists improvise over a strict left hand pattern, so I'm starting to think...is it really just too much for the brain and it's something left for composition? Or can I actually improve my left hand accompaniment skills?idk man I'm just rambling but if you guys have any tips i'm all ears
