The A minor scale is the most easy minor scale to learn on the piano and follows on quite nicely after learning the C major scale. The A minor scale is the first minor scale I teach students starting with 1 and 2 octave hands separately and only once this is mastered would I suggest trying them hands together. There are 3 variations of the A minor scale including Harmonic, Melodic and Natural. I generally start students off on the harmonic minor scale (as demonstrated below) as this is the most simple to grasp as it use the same notes up and down the scale and is required for the earlier ABRSM piano grades. The Melodic minor (which has a raised 6th going up) and the Natural minor (which has a lowered 7th) are typically used in conjunction which each other playing the ascending Melodic minor going up the piano followed by the Natural minor going down the piano. However the Melodic/Natural minor scales are not a requirement to Grade 6 ABRSM piano and beyond. As required in the later grades you can also increase all variations of the A minor scale to 3 and 4 octaves by putting the thumb under again in the right hand and 4th in the left hand and repeating the fingering pattern again. You may want to consider obtaining an ABRSM scale book to give you a better understanding of scales. These can be sourced locally from music shops in Swindon as well as from online music retailers.

Here is the piano fingering for the A Minor scales as taught in my lessons:

One octave R.H (up) 12312345 (down) 4321321

One octave L.H (up) 54321321 (down) 2312345

Two octaves R.H (up) 123123412312345 (down) 43213214321321

Two octaves L.H (up) 543213214321321 (down) 23123412312345
