Instrument Family Typical Range Key Feature Cor anglais (i) ................ Alto Uses a double reed (ii) ................ Brass Tenor-bass Uses a slide to ...

Answer:

The completed table is as follows:

(i) Woodwind [1] - The cor anglais (English horn) belongs to the woodwind family. It is a double-reed instrument, closely related to the oboe but larger and pitched a fifth lower. Its tone is darker, warmer, and more mellow than the oboe's. The double reed means two thin strips of cane vibrate against each other when the player blows between them. Other double-reed woodwinds include the oboe and bassoon.

(ii) Trombone [1] - The trombone is the brass instrument that uses a slide to change pitch. Instead of valves (as on a trumpet or French horn), the trombone has a telescoping slide that the player extends or retracts to lengthen or shorten the tubing. This gives the trombone a unique ability to glide smoothly between pitches (glissando) and to play any pitch within its range, not just those defined by valve combinations.

(iii) Tenor-bass [1] - The cello has a typical range in the tenor-bass register (also described as baritone or low register). Its four strings are tuned C-G-D-A (from lowest to highest), giving it a range from approximately C2 up to around A5 in higher positions. The cello covers the tenor and bass registers of the string family, sitting between the viola (alto range) above and the double bass (bass range) below.

(iv) Percussion [1] - The xylophone belongs to the percussion family. It is a tuned (pitched) percussion instrument consisting of wooden bars arranged like a keyboard, struck with hard mallets to produce bright, penetrating tones. The xylophone is distinguished from similar instruments by its material and sound: the marimba also has wooden bars but uses softer mallets for a warmer tone, while the glockenspiel uses metal bars for a bell-like timbre.
