Brass Family (Junior Cert Music): Revision Notes

Brass Family

• The brass family is one of the four main instrument families in the orchestra.
• Brass instruments are made of metal (usually brass) and produce sound when the player buzzes their lips into a mouthpiece.
• They are often used for bold, dramatic effects in music.

1. Characteristics of Brass Instruments

• Made from brass or metal with a shiny, reflective surface.
• Sound is created by buzzing the lips into a mouthpiece.
• Valves or slides change the pitch by altering the length of tubing.
• Played by controlling airspeed and lip tension to change notes.
• Louder and more powerful than most other instruments.
• Used in orchestras, film scores, jazz, military bands, and pop music.

2. Instruments of the Brass Family

Trumpet

3. How Brass Instruments Work

1. Buzzing Lips – The player vibrates their lips inside the mouthpiece.
2. Air Control – Airspeed and lip tension control the pitch.
3. Valves or Slides – These change the length of tubing, altering the pitch.
4. Bell Shape – The large bell at the end of the instrument helps project the sound.

4. Role of Brass Instruments in the Orchestra

• The brass section is powerful and bold.
• Often plays fanfares, loud dramatic parts, or rich harmonies.
• Works with the woodwind and percussion to create dynamic contrasts.
• The trumpets often play the melody.
• The French horns, trombones, and tubas provide harmony, depth, and bass support.
