Orchestra Instruments: The Sounds of the Symphony

When you attend an orchestra concert, you’re immersed in the sound of dozens of instruments playing together to create beautiful music. But have you ever wondered about the history and purpose of each instrument? In this guide, we’ll explore the different types of instruments used in orchestras, their unique sounds, and how they all work together to create the magic of the symphony.

String Instruments

The string section of an orchestra is comprised of violins, violas, cellos, and double basses. These instruments produce sound through the vibration of strings that are played with a bow or plucked with fingers. The violins typically play the melody of a piece, while the violas provide harmony and the cellos and basses provide a deep, rich foundation to the music. Some of the most famous pieces of classical music feature the string section prominently, such as Vivaldi’s “Four Seasons” and Beethoven’s “Symphony No. 5.”

Woodwind Instruments

Woodwind instruments are named for the material they were traditionally made from, but they are now often made from other materials. This section of the orchestra includes flutes, clarinets, oboes, and bassoons. These instruments are played by blowing air across a reed or through a mouthpiece. They are known for their ability to play both high and low notes with great clarity and expressiveness. Some of the most famous works featuring the woodwind section are Mozart’s “Clarinet Concerto” and Prokofiev’s “Peter and the Wolf.”

Brass Instruments

The brass section is made up of trumpets, trombones, French horns, and tubas. These instruments are played by blowing air through a mouthpiece and using the player’s lips to create vibrations. They are known for their powerful and bold sound, and are often used to create the grandeur and drama of orchestral music. Some of the most iconic brass moments in classical music include the opening of Richard Strauss’s “Also sprach Zarathustra” and the triumphant brass chorale in Bach’s “Brandenburg Concerto No. 2.”

Percussion Instruments

The percussion section is made up of various instruments that create rhythm and texture, such as timpani, snare drums, cymbals, and maracas. These instruments are often used to add excitement and complexity to orchestral pieces. For example, Tchaikovsky’s “1812 Overture” features a prominent use of the snare drum and cannon fire sound effects to create a sense of battle and victory.


In conclusion, the sounds of the orchestra are created by a unique combination of different types of instruments. Each has its own history, purpose, and sound. When played together by a skilled orchestra, these instruments can create some of the most beautiful and memorable music in human history. Whether you’re a seasoned concert-goer or a new listener, taking the time to appreciate the individual contributions of each section of the orchestra can enhance your enjoyment of the symphony.
