Sonata form

Sonata has a form.
1. EXPOSITION, including first theme, transition, second theme, and coda.
2. DEVELOPMENT. This part is like a solo part in modern music. This is where the composer show off his composing ability. That's why this part is normally complicated, jumping from one chord to another.
3. RECAPITULATION. Here is the summary of the song. We will go back to the first theme, transition, second theme, and coda.

Attitude

When you read music even if its just a sight reading make sure you play it with the right attitude. Most of the time I find myself just reading the music without paying attention to the dynamics or the little details like slure or rest sign.

Even when you just read music casually you must play it with the attitude to present the music nicely as if you are on stage.

Everything starts from a simple habit. Make it a habit to read and play music with an attitude, do it properly :)
