If you transpose the trumpet parts down one whole step you'll have the right transcription. B-G-B C-A-C F#-F#

However I think the root accent notes you hear (that aren't in the transcription) are E-E-A-A-F#-F#
The accents being on
1, 2, 2and, 3and, 4, 5

I do not work here, but the benefits are still awesome
