Its been a while since the last activity here.
I had a long talk with an old friend of mine yesterday, also a musician and teacher. In that discussion i realized that there where three things that made me play better. All three being "renderings" or "visualizations" of mental processes. Also they are best practiced and performed with your eyes closed.
1) The first one i would like to call a "temporal rendering" i.e being aware of the temporal aspects (meter, tempo, rhythm, how you play relative to the beat etc) of your playing, and ultimately having control over them. There is a exercise called "the magic clap" wich helps this a lot. Also ALWAYS tapping your foot enhances this awareness
2) The second i would like a "audible rendering" in lack of better terminology. To have a mental image or to actually "hear" what you are playing inside your mind at the same time (or maybe a little before) you are actually doing it.
3) The third one i would like to call a "motoric rendering". By this i mean that you are aware of both the position and the movement of your fingers (or feet or lips or..) without actually having to look at them. When i play with my eyes closed i can acually "see" both my hands performing
Focusing on these and practicing them has helped me a lot.
