That is step #2 JoeGuam. Once they get a handle on the basic three chords, I show them that the Am is just the upper half of the F chord. "
Make an F chord then point at me with your index finger".
With the Am chord too, I show them the 50's progression -- C-Am-F-G7 and quickly run through snippets of a dozen songs to illustrate how powerful and common that one is. Then turn the progression around or mix it up a little and play songs like "Let It Be" and "Wagon Wheel". And the Iz version of "Somewhere Over the Rainbow". And "Amazing Grace". And.......
I too like the Kala tenor models, especially the thin body travel ukes. Louder than you would expect, and always set-up well and intonated correctly.
