Welcome to... "Micro-Lesson 235"
The sixteenth-note triplet melody operates between the "F Natural Minor" scale and the use of both "F Minor" triad arpeggios and other diatonic arpeggios from the key.
In measure one we find a short "F Minor" triad arpeggio that is built from the root of "F" and then doubles-back across the chords. Measure two, carries along from there and runs across another pattern of our "F Minor" arpeggio.
Measure three uses "Bb maj, Ab min., and G diminished" arpeggios to bring in our ending idea which pushes on the notes of "G and C" to produce a triumphant ending. The patterns are fairly manageable, however if arpeggios and faster scale lines are somewhat new to you it would be best to commit this melody to memory.
Once the ideas are able to be played from memory, turn on a metronome and start increasing the tempo until the parts can be played quite quickly. Enjoy!
