Brass Family

Brass Family instruments produce their unique sound by the player buzzing his/her lips while blowing air through a cup- or funnel-shaped mouthpiece. The main instruments of the brass family include the trumpet, horn, trombone, and tuba.

Trumpet

The trumpet makes the highest pitched sound of the brass family. The trumpet sound travels through about 2 metres (6 ½ feet) of tubing bent into an oblong shape.

Trombone

The mouthpiece of the trombone is larger than that of a trumpet, and gives the instrument a more mellow sound. Instead of valves, the trombone has a slide which changes the length of its approximately 2,7 metres (9 feet) of tubing to reach different pitches.

French Horn

The horn or French horn consists of about 3,6 metres (12 feet) of narrow tubing wound into a circle.

Tuba

The tubing in this instrument is about 4.8 metres (16 feet), and it has the lowest pitch in the brass family. It incorporates four to five valves and the player holds it upright in his lap.
