This Trống cơm rendition has one female and 4 male voices, in Quan họ dialect, accompanied by trống cơm [rice drums], sáo [flute], and đàn nguyệt [moon lute]. We use freeware, vocalremover.org and vocali.se to separate the voices from the accompanied instruments. We then fed the mp3 singing voices into Anthemscore, Sonic Visualiser and Vista Voce to pick out the best voice separation algorithm. Our aim is to find the best rendition of spectrographic data to transcribe into a tablature. This is the output tablature, where all acute sắc accents are marked by a suddent jump in spectrogram and can be mimed on đàn tranh by mổ [taps], ... the concave tones hỏi ngã are rendered as nhấn [bend] followed by vuốt [release], the level tones ngang [high level] and huyền [low level] can be rendered as rung [vibratos]. Thus, the tones are the sources of hoa lá cành, and lòng bản is a performed piece without tonal influence on the melody nor the standard Á glissandos, nor song thanh octave blocks or arpeggios and three string plugs, nor national or regional dialectal variations of string patterns of rung [vibratos].

Pòng pong, there is a rice drum
Praise the one who plays it flowery pòng pong,
Which prompted a bunch of eager kids,
wading and swimming across the rivers, looking for
the one who fancies your heart and turns your eyes dreamy
It's a band of intoxicated spiders, pòng pong,
the band of drunk spiders, pòng pong.
They spin confusing webs hoping to catch
the one who fancies your heart and turns your eyes dreamy
It's your sweet fate with a handsome vagabond.
