I’ve been doing some research on the great American songwriter Irving Berlin and something struck me as odd. Several sources claim he never learned to read or write music. While this is certainly believable for later songwriters with easy access to recording equipment, how was Irving Berlin able to pass his songs along to live Broadway orchestras without a transcription? Is this folklore, or did he come up with some way to write music without writing down the notes? –Patrick Gary, Dallas

Yes, it’s true. The composer of countless beloved standards and show tunes including “Alexander’s Ragtime Band,” “White Christmas,” and “God Bless America” couldn’t read or write music. As you rightly suppose, neither can lots of modern songwriters, but here’s the thing: musical illiteracy wasn’t all that rare in Berlin’s day either. Fact is, if the music industry thinks you’ve got enough commercial potential, it’ll likely figure out a way to compensate for your technical deficiencies. All you need to do is come up with the hits.

Getting tunes down on paper wasn’t Berlin’s only challenge. Having limited skills as a pianist, he couldn’t easily change keys. Not to worry. Around 1910, as his career was starting to take off, he bought an upright “transposing piano” for $100. To one side of the keyboard was a small wheel. Turning the wheel shifted the keyboard right or left
