One of the attractive properties of the pentatonic scale is that it harmonises so well with itself. The simplified five-tone pentatonic scale doesn’t use the fourth or seventh of the major scale – both of which are a semitone away from another scale degree, so potentially more dissonant..
As a result, the pentatonic scales are excellent for improvising (‘jamming’), as none of the scale-tones sound too objectionable played against any other.
Several rock bands have exploited this to the full, the Grateful Dead and the Allman Brothers particularly.
The Allman Brothers regularly played long improvisations on a pentatonic tune popularised by folk singer Donovan as ‘Mountain Song’. They called it ‘Mountain Jam’ and a recorded version appeared on their album ‘Eat a Peach’.
The Allman Brothers jam in E, and Donovan’s recording is in A. This keyboard version is in all-white-key C pentatonic major. The middle section is from the Allman Brothers’ version.
Write out a pentatonic shorthand version to transpose, or transpose the download MIDI file on MidiPiano and try playing along with Allman Brothers or Donovan YouTube performances.

The manic Stevie Wonder riff from Sir Duke (Songs in the Key of Life) at 1:04 on this recording:
This riff is in B major pentatonic (four black keys) and uses the chromatic sharp 2 as well.
As a keyboardist, you’re entitled to use your ‘Transpose’ function for this one. Take the keyboard down a semitone and play in C.
Two pieces by the Crusaders – Chain Reaction and Stomp and Buck Dance are in B flat minor pentatonic. That’s four black keys on the keyboard, but if your keyboard has a ‘Transpose’ function, you can set it down two semitones and play along in C minor (only two black keys).
Until the guitar break at 2m30s, the themes on Chain Reaction are pure diatonic (five-note) minor.

The major pentatonic scale tunes are often first choice when it comes to melody-writing – making work with the pentatonic scales invaluable for playing by ear.
Many tunes are almost pure pentatonic, with just the occasional added note - usually much out-numbered.
Here are two examples.
