I wish this had been available when I started playing piano as I was not a gifted ear player. In fact, I struggled. On top of this my teachers didn't stress aural development either. They were all readers first. So, my development was glacial. Thankfully, things have changed for piano students.
How did I develop my sight reading and aural skills? In college I was given proper ear training. Later, I took up the drums, learned countless tunes by ear, and wrote them down. For the last decade I've been teaching online where I don't always see students' hands clearly. My ear learned to hear individual notes out of place. My sightreading developed early because I was a lazy student. It was more fun to read tunes than to practice them. Consequently, I became a professional sight-reader. I still am.
If I can help you, call me.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
I'm a professional pianist and music educator in West Toronto Ontario. I'm also a devoted percussionist and drum teacher.
