The Gaussian function is the archetypal example of a bell shaped function. A bell-shaped function or simply 'bell curve' is a mathematical function having a characteristic "bell"-shaped curve. These functions are typically continuous or smooth, asymptotically approach zero for large negative/positive x, and have a single, unimodal maximum at ...
A mute cornett (French: cornet muet, German: stiller Zink, Italian: cornetto muto) is a straight cornett with a narrower bore and integrated mouthpiece carved into the end of the instrument's body. [13] The instrument tapers in thickness, until at the top it is about 1.3 centimetres (0.51 in) wide. [13]
The bell-shaped or contour nozzle is probably the most commonly used shaped rocket engine nozzle. It has a high angle expansion section (20 to 50 degrees) right behind the nozzle throat; this is followed by a gradual reversal of nozzle contour slope so that at the nozzle exit the divergence angle is small, usually less than a 10 degree half angle.
Unlike the trumpet, which has a cylindrical bore up to the bell section, the tubing of the cornet has a mostly conical bore, starting very narrow at the mouthpiece and gradually widening towards the bell. Cornets following the 1913 patent of E. A. Couturier can have a continuously conical bore. This shape is primarily responsible for the ...
Arban’s complete celebrated method for the cornet or E♭ alto, B♭ tenor, baritone, euphonium and B♭ bass in treble clef Subtitle newly revised and edited by Edwin Franko Goldman
The third volume, published in 1915 as Clarke's Characteristic Studies for Cornet, contains a "Treatise on Tongueing" about single, double, and triple tongue technique, 24 characteristic studies inspired by violin methods and progressing alternatingly through the major and minor keys chromatically ascending, and 15 solos. It is considered a ...
The bore of a baroque recorder has a "reversed" taper, being wider at the head and narrower at the foot of the instrument. [3] Most contemporary recorders also have such a conical bore as they are made very similar to baroque recorders. However, multiple renaissance, medieval and also modern recorders have a cylindrical bore.
