A slide in pitch between notes. Valve/lip
glissando involves hitting as many harmonics as possible between two
pitches. This is the standard glissando, but it is also possible to
use the hand to slide a semitone.
trills work anywhere on the instrument. Whole tone trills can be more
difficult, especially in the low to middle register. Lip trills between
two harmonics work well in the upper and middle registers.
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.
