Tenor folk shawm

thingiverse

The shawm, a loud medieval precursor to the oboe, features a straightforward six-hole fingering system. I am particularly impressed with its finger spacing of 32mm between holes and its ability to play an octave and a half. The pitch resembles that of a soprano voice (a tenor note elevated by one octave). Thanks to John Boshua for his exceptional ABS plastic print. To hear the instrument, visit http://soundcloud.com/paul-francis-harrison/ja-nuns-hons-pris-shawm. To print this shawm, consider your printer's capabilities and choose to print it as a single object or in segments. I have provided STL files to allow for printing in one run or separately. The shawm in the photos was printed from ABS plastic in two sections with a layer size of 0.1mm. For the reed, create a drinking straw reed using the instructions here: http://www.instructables.com/id/Practice-double-reed-from-a-drinking-straw/?ALLSTEPS. The straw should be 4-5mm in diameter. If the joints don't fit together perfectly, sand them until they do. Apply grease for tight seals between all joints and the reed. Fingering is simple, following this chart: http://www.logarithmic.net/pfh-files/design/folk-shawm-fingering.pdf. Additional shawm sizes and designs with more complex fingering systems similar to recorders are available in the "pre-built" design pack downloadable from http://www.logarithmic.net/pfh/design.
