I was thinking I needed to buy a tuner on Amazon because my mandolin was set up, but it had been a while and I wanted to learn to play. Something made me check the App Store though, and sure enough, there are several to choose from to help tune a mandolin and even learn chords. Wow. I’m constantly amazed at this age we live in. I can even learn to play the instrument for free online. I must be really old because technology isn’t just ordinary to me, but a source of wonder. I love science as much as I love art.
