For this acoustic pattern I've been using Processing to show the deflections of the volume relative to time. That means you only see what you hear. The quieter the song, the darker and narrowed the squares are. In top of the sound spectrum, the cello is drawn with his four strings and the individual fret, so that you could theoretically re-enact it.
