I cannot IMAGINE any grade 8 pupil being able to play melodic minor formula patterns in in ALL keys, with the hands separated by a 6th!
SCALES AND ARPEGGIOS * : from memory, in the following keys:
C, D, B, F # , F, E b majors and minors
A b major and G # minor, D b major and C # minor
Scales: legato or staccato, as directed by the examiner:
(i) in similar motion with hands together one octave apart, and with each hand separately, in the above keys
(minors in both melodic and harmonic forms) (four octaves)
(ii) in similar motion with hands together a third apart, and a sixth apart, in the above keys (minors in
harmonic form only) (four octaves)
(iii) legato only, in thirds with each hand separately in the keys of C and B b majors (two octaves)
Chromatic Scales: legato or staccato, as directed by the examiner:
(i) in similar motion with hands together a minor third apart, beginning on any notes named by the examiner
(four octaves)
(ii) legato only, with each hand separately, in minor thirds beginning on A # /C # (two octaves)
Arpeggios: legato only, in similar motion with hands together one octave apart, and with each hand separately:
(i) the common chords, in root position, first and second inversions, of the above keys (four octaves)
(ii) dominant seventh chords, in root position only, in the above keys (four octaves)
(iii) diminished seventh chords beginning on any note named by the examiner (four octaves)
Correct, minors in 6ths are harmonic. Melodic would at least sound musical!
It was the 'from memory' bit that got me in hot water. And, as I said, you're right the improvement will be amazing but... How long you spend on scales etc. per day? If one is not a concert pianist I think it'd be hard to push yourself.
