lots of patience kapatid,
for music schools you teach many peeps pero lower rates hundred plus to two hundred maybe but you are assured of students
for home service,you have to hunt your own and build reputation, but rates are higher around 500 more or less
for materials most of the music schools require you to know how to read notes and teach them notes rather than widow
i suggest realistic method for rock ba yun by carmine appice,you have to be flexible,magtuturo ka ng mga bata,mga baduy na mga kpop songs,etc,and you have to learn all styles kasi may mga mapapadaan na advance students,hehe,and wag mo damdamin na dapat alam mo,drums and music and general is a continous study,dati i can't teach double pedal,i tell my student i can't pero now i know some stuff.
and laslty,patience ulit,lalo na sa mga bata.
