Grade classification...

How do they decide the grade of a song? Fairly simple question

Well a simple answer would be the level of difficulty in each piece.

They judge difficulty mainly by, the speed it's played at, the rhythms used, the dynamics required, the overall length of the piece and some things like that. Now, keep in mind I'm not the guy sitting there who decides the grade, so that doesn't mean I REALLY know what i'm talking about! ^_^ This is all my understanding from why I see one piece put in a higher grade than an other.

The importaint thing here is that you don't think of pieces as grades. because when the pieces were composed themselves they were composed as simply "pieces of music" that the composer wanted to write. They weren't written with the intention that it would meet some random grade 5 level.

All songs no matter what grade are pieces of music and whether you play grade 1 or grade 10 you should give equal amount of respect and effort into playing each piece your VERY best!

My teacher once told me "Every second you're at the piano you should be making real music"

Think about it ^_^ it's easy for us to sit down and just "play the notes" and not make real music, we just make noise...
