Guitar exercises : Increasing finger speed

There are 6 strings numbered 6-1 from top to bottom, labelled E A D G B E respectively and 20 frets.A good strumming exercise to increase finger speed is pluck the first 4 frets of 6th string ,then first 4 frets of 5th string and so on upto 1st string.. Then pluck the 2nd,3rd,4th,5th frets of 1st string,then of 2nd string and so on upto 6th string. In this manner proceed upto the last fret..

Also keep practising the scales as regularly as possible..

Now onto a trick to identify chord families. It's the 1st, 4th and 5th chords when taken in alphabetic order(A-G-A..) starting from the main chord..For eg to find the chords in G major family write G A B C D and choose the 1st, 4th n 5th. Thus the chords in G major are G C D..Similarly for A major A B C D E, the chords in the family are A D E..

For more tips refer to the included video on guitar tips by the master himself, Joe Satriani..I've tried his exercises and believe me they are damn effective if you practise on a regular basis..
