And whatever the change of pitch, there was no loss of power, of integrity.

A verandah is on the north side, under the main roof with a slight change of pitch. A broader skillion is on the south side, again under the main roof but with a slight change of pitch. The roof is of corrugated steel, with exposed battens at the ends indicating the original timber shingled roof. The house has chamfered weatherboards to the gable end.

Skilled performers can use their embouchures to considerably alter the tuning of individual notes or produce vibrato, a pulsating change of pitch often employed in jazz. Vibrato is rare in classical or concert band literature; however, certain clarinetists, such as Richard Stoltzman, use vibrato in classical music. Special fingerings may be used to play quarter tones and other microtonal intervals.Lawson, pp.

Raised elevators push down on the tail and cause the nose to pitch up. This makes the wings fly at a higher angle of attack, which generates more lift and more drag. Centering the stick returns the elevators to neutral and stops the change of pitch. Some aircraft, such as an MD-80, use a servo tab within the elevator surface to aerodynamically move the main surface into position.

Vibrato (Italian, from past participle of "vibrare", to vibrate) is a musical effect consisting of a regular, pulsating change of pitch. It is used to add expression to vocal and instrumental music. Vibrato is typically characterised in terms of two factors: the amount of pitch variation ("extent of vibrato") and the speed with which the pitch is varied ("rate of vibrato"). In singing it can occur spontaneously through variations in the larynx.

It was soldered to a mouthpipe, which in turn was often soldered to the body of the instrument and strengthened by a crosspiece, as was also the bell, rendering the horn more solid. The sound they produced was called a recheat. Change of pitch was effected entirely by the lips (the horn not being equipped with valves until the 19th century). Without valves, only the notes within the harmonic series are available.

Change of pitch was controlled entirely by the lips (the horn not being equipped with valves until the 19th century). Without valves, only the notes within the harmonic series are available. By combining a long length with a narrow bore, the French horn's design allows the player to easily reach the higher overtones which differ by whole tones or less, thus making it capable of playing melodies before valves were invented. Early horns were commonly pitched in B alto, A, A, G, F, E, E, D, C, and B basso.

The timber frame additions are externally clad with horizontal weatherboards and internally with fibrous cement sheeting, similar to that found in the front rooms of this building. To the north west of the homestead, abutting its verandah on this side, is a one-roomed timber building known as the Dining Room. This is thought by the Lawless family to be the oldest building on the site. The building has a hipped corrugated iron roof and verandahs to the north east and north west, the awnings of which are incorporated in the main roof made discernible by a slight change of pitch.

It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842. A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer. Compared to the emitted frequency, the received frequency is higher during the approach, identical at the instant of passing by, and lower during the recession. The reason for the Doppler effect is that when the source of the waves is moving towards the observer, each successive wave crest is emitted from a position closer to the observer than the crest of the previous wave.

The process of talking underwater is influenced by the internal geometry of the life support equipment and constraints on the communications systems as well as the physical and physiological influences of the environment on the processes of speaking and vocal sound production. The use of breathing gases under pressure or containing helium causes problems in intelligibility of diver speech due to distortion caused by the different speed of sound in the gas and the different density of the gas compared to air at surface pressure. These parameters induce changes in the vocal tract formants, which affect the timbre, and a slight change of pitch. Several studies indicate that the loss in intelligibility is mainly due to the change in the formants.
