While playing the music sounds often incredible, but later when I listen to the recording it doesn’t sound good at all. The problem is that if you take any consecutive 10 seconds they sound great, but if you listen to 30 second recording it doesn’t make any sense at all. I am not aware of more that the last few previous seconds while I am creating new music.
What can I do for this that is not boring or a supplement to take?
That said, there’s the germ of a good question in there.
I too would like to improve my musical memory for complex melodies and harmonies.
It’s one thing to remember a simple pop tune accurately. It’s another thing altogether to remember, say, a twelve-tone row after one hearing, and yet it’s quite useful if one wants to appreciate variations, etc. that will come up later in a piece of music.
Practice. Not kidding! Play something complex and then play it from memory. Add a bar or two as you become more proficient.
I don’t know any way to get better at anything to do with music besides the grind of conscious repetition. At least, I never found any other way myself.
Tantalizing question! I consider my own “musical memory” to be “above average” but it is far from any “perfect pitch.” I know from experience that some complex melodies require my sitting down at the piano or noodling around on my guitar to be sure I’ve replicated the nuances to the more difficult ones. Those can be a major challenge, even after seeing the sheet music or replaying them on the record player. I don’t know of any simple methods for overcoming the lapse in whatever skill that may involve but I do know from experience that it can happen – with practice and patience.
I’m looking forward to more technical explanations others may have to this question!
Not sure if OP refers to not being able to play from memory (without relying on notation). It definitely gives your memory a workout, and it may be coincidence but I’ve noticed that functionally illiterate musicians usually have good memories and sharp minds.
About playing without a score, after memorizing all the parts of a piece, you have to remember the order of those parts and have some kind of name for each part (e.g., “weird arpeggios”), so there may be some kind of abstract thinking involved.
I think the OP is asking how to improve their composition skills so that an an improvised piece of live music has structure and stands up as a “song” in retrospect rather than just a bunch of musical ideas. IMO, unless you are an exceptional individual, you can’t, not while truly improvising. You either need to have some basic song structure in your head that you can play over/with, or you edit your raw recording to create structure after the performance. In the first case it’s not completely spontaneous, and the second won’t be a true representation of the performance.
The key to which method you use would be whether you are composing, in which case it doesn’t matter if the raw performance lacks structure, or you are performing, in which case it doesn’t matter if you are using the skeleton of a song to base the improvised performance on.
I like to improvise (and I do mean improvise) shit on my digital piano while recording, doing some rather normal things and occasionally going off on a tear with whatever nutty idea (or lack of an idea, to be precise) occurs to me. Almost invariably, when I play it back I enjoy it immensely and am quite impressed. This means that either I am a musical genius, or I have absolutely no musical taste whatsoever. Hmm. I wonder which one is the case?
