Okay, so I have a habit of asking questions that depend a great deal on the individual pianist and so can hardly be answered with any precision, but it's a habit that's hard to shake, so I'm here to ask another.
I watched a Josh Wright video where he plays a scale at up to 220 bpm, with four notes per click. This got me wondering what some reasonable BPM goals would be for the various scale types, for an advanced pianist like me. I'm by no means a virtuoso, and I've got a lot of deficiencies in technique to correct (hence my wanting to set some scale goals to work towards). I can play most major and minor scales hands together at about 140 bpm, or hands separately around 150. My current goal for this year is to get up to 180.
But in trying to set goals for, e.g., scales in double thirds or octaves, I found myself unsure of what goal I should set. What speed do you think most professional pianists could play double thirds scales at? What about scales in octaves? I suppose it also depends on the scale, since some are more awkward than others.
Also, I'm not accustomed to practicing double notes scales consistently. While I have not tested my limit for scales in thirds, I'm sure it does not exceed 85-90 bpm.
