We live in the information age. There is an endless supply of free educational content out there. In general, drummers are curious and determined people. So, when you combine determination, curiosity, and free educational resources, it seems that drummers have everything they need to progress.
So, why do we pay drum teachers to teach us?
To be more specific: What do we expect from a teacher that we can't get for free online? - Do we expect motivation when we need it? Do we expect a physical trainer-type character to keep us in check? Do we expect more detailed and applicable information?
Of course, there are many varying opinions on this topic. However, if possible, I'm looking for a semi-objective answer that represents the general community of drummers.
