If I hear a note I cannot tell you what it is from memory, but I can go to a piano keyboard and play that note. If I hear a song, I can play the melody and build the cords easily, with awful technique since I had never had piano lessons.
I am amazed by those who can go into a foreign environment and tune a piano by ear, with no tools or meters, and have it in perfect tune.
I am in retirement for a year. I want to now take piano lessons. I will start soon.
Good for you. There are many teachers who would say don't bother; you're too old. Ignore them and enjoy it.
In other words spousal selective hearing or pushing the mute button
I have that mute button. Took years to develop. Evolution.
