After testing in every direction, left-to-right is a West End farce, but the rest is workable. So long as I don’t have the frame limiting mobility – it’s going to have to be moved fairly often or skipped altogether.
Straight lines are always harder than they look. Harvested another practice block from the Basketcase scraps and, after the first lines went wavy AF, taped it up. Vast improvement. Stitch length still needs work , but the back is worlds cleaner.
Although Iommi was untrained in music theory, he devised the three-note passage after listening to a piece of classical music he and bassist Geezer Butler enjoyed by Gustav Holst called “Mars, The Bringer of War” from the suite The Planets (written in 1914). The composition included a triad, and when Iommi imitated the sound on guitar he liked the unsettling feeling it created. He experimented with the passage and slowed it down to a crawl. Then he added a trill to the flatted fifth, repeatedly wavering from Db to D and added vibrato to the other notes to emphasize the tension of the music.
