jazzcore music is characterized by elements of a song, ie usually contain metal breakdowns, jazz chords, and hardcore riffs and leads, or possibly parts that combine all of these and more.

typical instruments used in jazzcore are:
guitar
b-ss
drums(with double b-ss drumming)
screamed vocals
clean vocals
potentially keyboards or synth

guitars in jazzcore usually tuned their strings down using varied tunings. while a metal guitarist might tune his strings in drop b tuning, a jazzcore guitarist might differ from that tuning (ie, b-f#-b-e-g#a, or a-f#-b-e-g#-a)
while metal guitarists may also use drop c tuning, a jazzcore guitarist may vary from this tuning by using cello tuning (c-g-d-a-b-e) this is done to make playing jazz chords and metal riffs at the same time a little bit easier.
