Hi I have started learning on electric guitar. I have practised chromatic patterns for a month now and I am pretty comfortable with it. Also I can roughly play certain instrumentals like Satriani - Ten Words, Wihspering a Prayer (half), etc. (basically slow songs), which actually motivates me to further my learning. Now I want to know what exercises to practise and for how much (avg.) time to steadily progress & develop speed, dexterity, etc. My goal is to eventually be able to play fast songs and shred. Is there a website/resource which can be followed for this purpose? Something which has routines that can be followed.
