How can you encourage other teachers to use the ed tech facilities? You may not know this, but there is not a lot of difference between a Lee Oskar diatonic harmonica (the type used by blues and folk musicians) and a Hohner Blues Band harmonica. The Lee Oskar is said to have been engineered to give a “sharper” edge to the tone, which suits the blues sound, whereas the Marine Band, being slightly “softer”, works well for folk music too. Unless you’re a purist, there is probably not much in it. As someone once said:

“A difference is only a difference if it makes a difference.”
