Input: Consider Input: [header] How to use sliding for blues guitar [title] Fret a note, play it, and slide to another fret without picking up your fingers. [step] A slide is supposed to be a continuous sound. You pick the note, holding down your finger, then slide up or down the neck while you can still hear the first note. <sep> (A) You should hear the pitch of the note move with your finger--getting higher if you move towards your body and lower if you move away. [substeps] A slide is noted on a tab by a slash. (B) Practice sliding along the neck so you don't need to let go of your left finger. Using slides doesn't change the pitch, so if you fret to another note you can change the pitch and move up the neck so you can hear the first note. (C) You don't have to start with the fret (repeat your previous step for good accuracy) before you can move onto sliding. Slide all the way up or down the neck until you reach at least two notes with only one fret without picking up your fingers. (D) Use only the wrist to slide up or down the neck of the guitar. [substeps] You might also try a faster slide because this lets you see closer to where you are, so at the least you get some effort from your finger.
