Artist Study songs - difficulty

Hi David,

I was wondering if the  technical level needed to play accuratly the artit study songs was related to the LOA which unlocked the songs.

I guess the answer is no since we can find some bends even in the first one for example.

Playing some other instruments, I know that a song difficulty level is not set in stone. But I know that I can lose some time trying to play something too much difficult regarding the current level I have, instead of working on other tunes/songs/exercises which will bring me new skills and help me later to master the firsts difficult song easily.

What do you think ? What would be the required lesson/LOA achivement needed in order to approach confortably those songs?

Regards,
