In a bit of a twist on who has the misconception, I get frustrated with many musicians who just don’t understand that there is a continuum of talent and expertise, and what comes naturally to them they often assume is common to others.
Example: I can happily play competent bass for professional-level musicians–I jokingly say that I only need to play one note while they play everything else. But it is super common to be asked “do you play by ear?” in the heat of the moment. No, I don’t. So please at least whisper the key to me so I can have a fighting chance at figuring out what you are doing. Part of my own homework is to be familiar enough with popular chord progressions that I can jump in with you as you improvise, but if I don’t know you are in Eb, I’m lost.
It’s not that they look down on me for it (at least the ones who were taught proper manners!) but they just assume that what is natural for them would also be natural for other musicians.
There is an outdoor event this weekend for our church organization that I will be playing at, and the setlist looked just fine, with Christian standards, but I had to kick up quite a fuss until someone finally said “This one will be G, that one in F, the other is in Ab.” and so on. That’s all I needed.
I won’t even complain when you randomly toss in a few crazy fills and then hop to the middle of the third verse again without warning–nobody notices when the bassist drops a few measures!
Aside from musicians assumptions, everyone else assumes “play by ear” is some magical thing that involves perfect pitch and the ability to play like Elton John at the drop of a hat. The reality is that even playing by ear is a continuum–though I say I don’t have this ability, I still do “play by ear” to some extent: I can recognize the sound of super common stuff like V7-I, ii-V7-I, I-vi-ii-V7 as they come around, and that informs my playing, but I most certainly wouldn’t be able to tell what any specific note was without noodling around the fretboard until I found it.
My wife, on the other hand, has some degree of perfect pitch, if she is calmly listening to someone playing a note by itself, she will say what it is, and she definitely perceives the same song in different keys as having different emotions or colors (baffling to me). She would not say she plays by ear though.
