I'm an Artisan Composer,
ISFP
I too have trouble with communication and conversation.
"Composers are just as plentiful as the other Artisans, say nine or ten per cent of the population, but in general they are very difficult to observe and thus greatly misunderstood. Very likely the difficulty comes from their tendency not to express themselves verbally, but through their works of art. Composers are usually not interested in developing ability in public speaking, or even in the art of conversation; they prefer to feel the pulse of life by touch, in the muscles, in the eyes, in the ears, on the tongue. Make no mistake, Composers are just as interested as other types in sharing their view of the world, and if they find a medium of non-verbal communication-some art form-then they will express their character quite eloquently. If not, they simply remain unknown, their quietness leaving their character all but invisible."
