The image that follows shows what Guitar Pro 6 describes as the Minor Pentatonic (5th mode of major pentatonic) - more commonly known as the G pentatonic minor scale. As usual this is totally indigestible by most guitar players (plus the Bb is misspelt as A#) and needs to be broken down into more manageable chunks.
