| The shawm, baroque oboe, baroque bassoon and dulcian can overblow without the use of a thumbhole. |
|
| Developed from the dulcian, the bassoon has never acquired a fashionable status among woodwind instruments. |
|
| Their difference is the shawm has only one bore, the dulcian has two and it is folded at the bottom. |
|
| The dulcian was made in several sizes and has a range of about two and one-half octaves. |
|
| Another marked difference between the bassoon and the dulcian is that as was common with other Renaissance instruments, it came in a consort or family. |
|
| He is also very active as a chamber musician on dulcian, baroque and classical bassoons, with engagements across North America. |
|
| Mallavibarrena and Abello chose to forgo that practice and lend extra support to the bass voices by doubling their parts using organ and dulcian. |
