Guitar practice randomiser
By Neil Downing

This page generates a random key so that when you are practising guitar you don't get bogged down using the same scales every time you play.

The suggested use is:

  1. Write down the notes in the key (don't scroll down yet!)
  2. Write down the chords in the key
  3. Write down the relative key (i.e. if you have a major, what's the relative minor, or vice versa?)
  4. Now scroll down to check if you were right
  5. Find the root chord (try to find a chord position lowest down the fretboard)
  6. Find the nearest pentatonic shape to the chord you've just found
  7. Play through the five pentatonic scales, starting with the one you've just found


Random key: B major

Disclaimer: As a guitarist, I have a stereotypical disregard for music theory and, as such, I have no idea when I should use the terms "sharp" or "flat" (e.g. whether I should call a note C# or D♭), so I have used "sharp" in all cases here.
