Hi Bernhard,
I actually applied this method to some difficult jumps i had without knowing its basis
being rather ignorant in biology, does your 'verbal-sound / visual' distinction apply to all people? Or should it be inverted for left handed people? (i write with my left hand but do most other things with both or the right hand). Second, does 'verbal' mean 'saying (or singing) the notes' as you play or merely 'thinking' them?
“verbal” means giving names to the notes, even if it is only in your mind. If as you play you “see” or “hear” the names of the notes/names of the chords, you are verbalising them.
In the majority of people verbalisation takes part in the left hemisphere of the brain. However, as with everything in the Universe, there are degrees of grey and nothing is only black or white.
Research on right/left brain hemisphere is very recent – the whole thing was discovered in 1967 by Roger Sperry (who subsequently got a Nobel Prize for his research).
Here is the story so far:
Right hemisphere of the brain (controls the left side of the body):
- Nonverbal (aware of stuff but cannot connect it with words)
- Makes synthesis
- Concrete (deal with things as they are, cannot abstract)
- Analogic (compares – understands metaphors – size more important than number)
- Timeless (no conception/feeling for time)
- Non-rational (conclusions not based on reason)
- Spatial (hence visual: see whre things are in relation to each other and how theu relate spatially – sense of perspective)
- Intuitive (ability to have insights based on incomplete information)
- Holistic (ability to see the whole pattern at once, even though the separate parts my appear contradictory. Sees the forest, rather than the trees).
Left hemisphere of the brain (controls the right side of the body):
- Verbal (uses words to describe perception s of reality)
- Analytic (figures things out step-by-step)
- Symbolic (uses symbols to stand for things. e.g., words)
- Abstract (ability to use a small bit of information to derive the whole)
- Temporal (aware of time. Keeps track of time)
- Rational (arrives at conclusions through reasoning)
- Digital (numbers more important than size)
- Logical (Draws conclusions based on logic)
- Linear (one idea leads to the next in a linear way, often arriving at contradictory conclusions).
Experts agree that the sharper is the specialization the better for the person. This is technically called “lateralization” (the degree to which specific functions are carried out exclusively by one of the hemispheres). People with less lateralization (that is, a function like verbalization is carried out by both hemispheres) are more prone to problems like stuttering and dyslexia. Incidentally this is one of the reasons teachers stopped trying to change hand-dominance in children (until recently you would be forced to write with your right hand even if you were right handed). It is now accepted that forcing a child to use the right hand if they are left handed can interfere negatively with the process of lateralization. If this happens you end up with right/left confusion, which is a surprisingly common condition. How many of you out there can tell left form right? If you say left and you are always pointing right, or the PE teacher (or army sergeant) shouts Left! And you are the only one who turns right, you have right/left confusion which is indicative of incomplete laterisation. It is no big deal.
So to answer your question: Your verbal function may be located in your left hemisphere (90% of right handers and 70% of left handers), it may be located in the right hemisphere (2% of right handers and 15% of left handers) or it may be shared between both hemispheres (8% of right handers and 15% of left handers)
How can you know which one you are? Apart from specific lab tests, just observe what you do naturally at the piano: What is the easiest for you? To pay visual attention to the LH while you play the RH by ear (use a two voice invention to test this, since the melody will be equally shared between both hands)? If so you are with the majority.
To look at the right hand while you play the LH by ear (then you are in the minority who have brain hemisphere functions reversed).
Both seem to work (or not work)? Then you have poor lateralisation (as I said it is no big deal, just make sure you are not the one giving directions to the driver!)
Perhaps the greatest tragedy of our educational system is that is so much left hemisphere oriented.
Finally: Music seems to be processed naturally in the right hemisphere, but professional musicians have a hefty left hemisphere contribution.
And a couple of years ago I saw a documentary on TV investigating the areas of the brain associated with different activities. A person had electrodes attached to his brain, and as he went through some activity, there was a graphic of his brain that alighted. So as he was reading, the left frontal hemisphere alighted, when he was eating, the back of his brain alighted, and so on and so forth. Then he was given a keyboard and started to play Bach’s Italian Concerto. His whole brain alighted like a Christmas tree.
Best wishes,
Bernhard.
