glissando

Glissando

A slide in pitch between notes. Possible on holed notes, but extremely limited on keyed notes. The contrabassoon

Available glissandi on the bassoon:
Glissandi on the contra:

mute

Mute

A soft object insterted into the end of the bassoon. Only effective in the bottom register of the bassoon and extremely rare on the contra.
Mute (bassoon):

tremolo

Bassoon Trills
A rapid alternation between two pitches. The notation above, read in treble clef, shows a minor trill followed by a major trill, indicated by accidentals over the note. If these are not given, players will choose trill type based on musical context. The wavy lines indicating duration of trill are also optional. Trills are all possible, except low down on the bassoon and the contra. Timbral trills are also possible.

The Orchestra: A User's Manual is a free resource and will remain so. It still receives between 8,000 and 16,000 unique visits per month from all over the world. See the testimonials. Thanks to all the donations, I have been able to create this responsive re-design. But the movies and sound clips recorded in 2004 do show their age. I would really like to re-record everything and add many more techniques, especially for solo and ensemble writing. I estimate this will cost around £30,000.
