How do they make sound?The woodwind family consists of piccolos, flutes,oboes, english horns, clarinets, bassoons, andsaxophones.With the exception of the piccolo and flute, the soundis produced by a vibrating reed.Different pitches are produced by opening andcovering holes along the instrument
How do they make sound?The brass family typically consists of trumpets, Frenchhorns, trombones, euphoniums, and tubas.Sound is produced by forcing air through themouthpiece.With the exception of the trombone, pitches arealtered by pressing or releasing valves.All brass players also tighten or relax their lips tochange pitch.
How do they make sound?The percussion family contains the most instruments.Some of the standard instruments include the bassdrum, snare drum, timpani, bells, cymbals, and thetriangle.Sound is produced by striking some part of theinstrument with a mallet, stick, or hands.Not all percussion instruments can produce multiplepitches. In most cases the pitch of the instrument isdependent on the size of the instrument.
How is the pitch of instruments determined?As was mentioned earlier, the biggest determiningfactor in the pitch an instrument produces is the sizeof the instrument.The distance that air travels in the instrument alsodetermines the pitch.
Generally…The larger and longer an instrument is, the lower thepitch.The smaller and shorter an instrument, the higher thepitch.
One of the easiest ways to see this is with the trombone.The higher the noteis on the staff, thehigher the pitch ofthe note.Notice how thetrombone slide getslonger as the notesget lower?
Some things you can try on your own:Hold a rubber band sothat it is stretchedbetween two fingers.Pluck the rubber band.Now, increase thedistance between yourfingers, stretching therubber band. Pluck therubber band again.
What do you notice aboutthe sound? Does it soundlower or higher thanbefore?Try the same thing withrubber bands of differentwidths. What do younotice?
