Unit 3: What is an Orchestra? An Orchestra is a loosely defined term that can be used to refer to any large collection of musicians playing together, usually on string, woodwind, brass, and percussion instruments.

Percussion instruments are a family of instruments that produce sound by being struck, shaken, or scraped. Examples of percussion instruments include drums, cymbals, tambourine, maracas, xylophone, and triangle. In an orchestra, percussion instruments provide rhythmic support, accentuate musical passages, and add a variety of sounds and textures to the overall sound.
Brass instruments produce sound by buzzing into a mouthpiece and using valves or a slide to change the pitch. The brass section typically includes trumpets, trombones, French horns, and tubas. Brass instruments are known for their powerful and bold sound, and they often play dominant roles in orchestral compositions, such as fanfares or majestic melodies.
Woodwind instruments produce sound by blowing air through a mouthpiece or reed. They include flutes, clarinets, oboes, and bassoons. Woodwinds can produce a wide range of tones and are often used for melodic lines, harmonies, and intricate passages in orchestral music.
Strings instruments are played by either plucking the strings or using a bow to create sound. The string section includes instruments such as violins, violas, cellos, and double basses. Strings can produce a wide range of tones and effects and are often used for melodic lines, harmonies, and providing a rich and warm sound foundation for the orchestra.
Together, the various sections of the orchestra create a harmonious blend of sounds, with each section contributing its unique tonal qualities and musical roles to create a diverse and balanced ensemble.
