Theory plays an important part in musical creation. Imagine what we might be missing out on if Beethoven couldn’t note down Moonlight Sonata or if Mozart couldn’t write down one of his many, many piano concertos (he was not a man of titles). There would be a terrifying history of music missed out on if it wasn’t for sheet music so we should be grateful to those who invented musical notes. If you’re not a play-by-ear kind of musician, then sheet music will play a vital role in your musical experience and you can find anything from classical to mowtown to soundtrack. Of course, it might not be the musical notes that offer you inspiration, but words and lyrics, so it’s a good job we also have a category alongside dedicated purely to song books. We just hope you twitter like a nightingale and don’t squawk like a parrot.
