They run up a diatonic scale (major or minor I couldn’t tell you) for 8 notes, slurred, with a big crescendo, then modulate up a half step, then run down the scale with a decrescendo, modulate up a half step again and go up the scale again, etc. This happens several times. These might be the notes:
