The Beauty of Movable DO
Once we learn how to read patterns in one DO-signature, the same patterns can be put in a different place, and the relationship between pitches will remain constant. The only thing that will change is where DO is. Once you understand and internalize this concept, music reading becomes a lot easier.
The letters of the musical alphabet answer the question, “Which DO?” Since DO is movable, we need to distinguish between DO-signatures. Letters help us do that. Think of them like proper nouns vs. common nouns: Which boy? Todd.
