A Hirajoshi (Pentatonic Scale) vs A Minor Pentatonic.
Here is a lesson using/comparing two pentatonic scales: A minor pentatonic (1 b3 4 5 b7 – A C D E G) and A Hirajoshi (1 2 b3 5 b6 – A B C E F). Both can be used when improvising over the A Aeolian mode (A natural minor). Make sure you start by practising slowly this new scale (if you are not already familiar with it) and ideally learn this all over the fretboard. It is not an easy task, but certainly worth investing the time to get there. A good guitar teacher could give you plenty of tips to master this scale in a relatively short time, but this may not be possible unless you seek some private tuition as it usually takes a few lessons to start 'controlling' the sound of this pentatonic scale.

6-Finger Tapping Technique Lesson
Here is a lesson using two pentatonic patterns from D minor pentatonic and a 6 finger tapping technique. To play the section with the tapping technique: you can use 3 fingers from your left hand (index, ring and little finger) and 3 fingers from your right (middle, ring and little finger if you prefer to hold the plectrum as usual whilst tapping notes on the fretboard). Make sure you start by practising slowly if you are not already familiar with this sort of technique.

D Dorian Backing Track

Here is a backing track so you can practise improvising over the Dorian mode in D. You can see a few theoretical concepts on the video clip with which you can improvise. These are by no means the only options, but a good starting point. It takes time to master those concepts all over the fretboard, so take your time. If you want to avoid spending ages to master them or if you don't know how to decode them onto the fretboard, consider giving me a call to book some lessons so you understand better how to improvise over modes.
