Having the ability to perform stretches, will allow you to easily perform passages that require stretching. As you no doubt know, there are many guitar solos that require you to stretch your fingers beyond one finger per fret.

However, having great stretching capabilities doesn’t automatically mean you will be able to play those lightning speed passages, that is unless you also work on improving your overall speed and accuracy.

In other words, to become a great overall guitarist, you will want to work on stretching, speed and accuracy exercises.
