My music theory is quite rusty never having really been polished to begin with, but here’s a challenge that I’m sure already exists, but occured to me just now.
Write a grammatical English sentence, no matter how simple, that is also musically valid, and by that in my simple understanding of the theory both melodic and resolved, using only the notes of the scale, c d e f g a b…
And let me just say that I have no idea if it can be done and if it can be, there’s no way I could even begin to attempt it myself.
Just in my head haha. I suppose that if you put it in a proper key and actually give it rhythm, it might sound bearable. But in the key of C with each note getting one beat, it is not a pleasant tune at all.
If you allow some leeway and some creativity you can get a few extra letters. For example in German music notation the note B-flat is denoted by the letter H. And with a little more creativity you can get a few additional letters.
Dmitri Shostakovich used the motif D-S-C-H in his 5th and 10th symphonies. DSCH stood for his name. D for Dmitri and SCH for Shostakovich (it probably makes more sense when spelled in Russian).
Anyways, here’s a web page explaining some of the creative musical spellings: A Musical Spelling Lesson
