My final point is to think about your instrument or gear setup, and anything else you’d want to dress the stage with. This one may take some years to fully conceptualize and realize, and it may be something that changes constantly. That’s all okay, but just know that it too matters.
Whether you’re a vocalist learning to sight sing from sheet music or an instrumentalist working on transcribing songs, arranging for an ensemble, or even composing new musical material, learning to identify intervals by ear can be useful across almost any situation. Plus, if you can identify intervals by ear, who needs perfect pitch?
