I once took on the task of teaching a class of about 20 kids, from grades 4 to 7, who had never played before. The human mind has a protective mechanism that causes memory loss during traumatic incidents, so that period of my life is kinda hazy. LOL.

What I do recall, though, was they didn't want to learn scales, or details of technique. They wanted to play a song. I took a big chance and asked them what song they wanted to learn. They agreed on "Proud Mary" by Credence Clearwater Revival. (This about 25 years ago).

Because they had all agreed on that song, they were motivated to learn it, and they helped each other with it. There was a school assembley/PTA meeting a month later. The parents were treated to "Proud Mary" played by a massed chorus of 20 guitars! :D

Good Luck!
