 So here's how to choose a scale for a song if you're a piano player or a singer. First of all, understand the difference between a scale and a key. When you make a decision with respect to vocal range, remember it's with respect to the song and the intervals you're going to encounter in the song. If you sing and play the piano and if you're figuring out the scale of the song, do not transpose your piano ever, rather transpose the actual song. As a singer, when you're figuring out the scale of a song, it's important to push yourself slightly above your comfort zone and also try to warm up before you make a decision. If you're a piano, you need to know that every scale is a different playground. And lastly, some ways to be professional. Decide and communicate with your bandmates and your choir and everyone well in advance. Understand the challenges faced by instruments like guitar and horn and then take an informed decision.
