Right hemisphere

The right hemisphere processes information from whole to parts. Usually it sees the whole picture first before the details. If you are right brain, it may be difficult for you to follow a lecture without the professor had given the outline first. If that is the case, it may be best for you to read the chapter before class or ask the professor to give you the topic and outline of the next lecture. You may also have trouble writing outlines if you are right-brained. You would write the entire paper and then last, the outline (if required).
The right hemisphere is spatial orientated, recognizes sequencing of symbols, objects, and events, appreciates music, non-verbal, emotional, empathic, witty and humorous. Other functions consist of drive, order, planning, and executive control. Some problematic characteristics, which exist in the right hemisphere of the brain, are emotional comprehension and procession of symbols.
Right brain students know how they feel but have trouble expressing it in words.

George Harrison
I think he used the right side more because he was a successful musician and it helped him in his career because it influenced him developing his abilities on music such as playing guitar, singing, songwriting and as a film producer who achieved international fame as lead guitarist of The Beatles. Harrison is listed at number 21 in Rolling Stone magazine's list of "100 Greatest Guitarists of All Time".

Ludwig van Beethoven
I think he has more developed the right hemisphere because he had abilities on music; he was a great composer and pianist. He is considered to have been the most crucial figure in the transitional period between the Classical and Romantic eras in Western classical music, and remains one of the most famous and influential composers of all time.
