I'm church music composer Myung Whan Kim, going by Johann Kim who writes new praise art music and hymn arrangements for various instruments, now teaching at the Southern Baptist Theological Seminary as adjunct faculty. So far more than 50 works have been published by New Praise Support Edition, among which many are hymn arrangements and new art music for piano. Bell harmony is the most important harmonic world to me which I have developed since last twenty years.
There are some helpful links which might be crucial to understand my music world.
God bless you!
