Hi, just a quick question - do you want to pursue a musical career and do you play any instruments?
I am yr10 and I'll try to help if I can. My music teachers have always been good tbh so I can't relate on that front, but revision tips - flashcards, past papers, note-taking, repeat repeat repeat. Seneca is good, I do Edexcel GCSE, you might not, but Seneca has the entire exam board on there. For various musical elements, make boards with all good words on, for example -
Melody:
Ornamentation
Melisma
Syllabic
Repetition
Descending
Ascending
Conjunct
Disjunct
Anacrusis
Ostinato
Articulation
Call and Response
Sequences
Rhythm:
Cross-rhythms
Duration
Ties
Polyrhythmic
Ostinato
Note values
Straight
Dotted
Rests
Offbeats
Notes
Swung
Harmony:
Cadences
Harmonic devices - suspensions, sequences, circle of 5ths, pedal note, cadences
Dissonant chords
Tierce de Picardie
Diminished
Major
Minor
Augmented
Chords
Consonant chords
Tonality:
Atonal
Pentatonic
Whole tone
Chromatic
Major
Minor
Modal
Also, the DR SMITH method is useful.
D - dynamics; duration
R - rhythm
S - structure
M - melody; metre
I - instrumentation
T - texture; tempo; timbre; tonality
H - harmony
Are you doing Music For A While as a set piece? Because I can send my revision notes over if that's helpful
