2. Percussion instruments are designed to make unique noises when it is hit with a stick or a hand. There are two different groups in the percussion instrument the are; membranophones and idiophones. Membranophones- An instrument that has a stretched membrane covering a hollow shell. Idiophones- An instrument that makes sound by itself. Rhythm – percussion instruments are in charge of the rhythm. Drums support the music and keeps the time Mallet – The hand/stick which causes the instrument to vibrate to produce noise. Pitch- Each drum is tuned to a certain note Drum machine –Creates a vast number of percussion sounds Percussion

3. Brass Instruments Wind instrument- An instrument you play by blowing through it. Vibrate- When you hold your lips tightly together to make a high pitched buzz and relax them to make a low pitch buzz. Pitch- The longer the tube the lower the pitch, it also depends on the width. Brass- Instruments made from brass don’t necessarily belong to the brass group. Brass instruments are long metal tubes. Tone- Buzzing lips against the mouthpiece causes the tube and air inside to vibrate creating a clear tone. Valve- Players changes the pitch of notes by pressing down on a series of these.

4. Woodwind Woodwind – these instruments are all not made out of wood but requires wind to make a noise. They have holes in the instruments. Mouthpiece- you blow air through this this is also a reed. Without these woodwinds cannot produce sound. Reed- it is normally made out of bamboo. It is the vibrating air produced inside the instruments, blown through the reed within the mouthpiece. Edge-blown – Air is blown over the mouthpiece. Single-reed – They have a single reed in their mouthpiece which vibrates to get the air inside the instrument moving. Double-reed – The oboe uses this and produces even more vibration. All woodwind instruments have a series of notes running down its length.

5. Strings Plucked – The string is flicked with a thumb, finger or a small piece of plastic. The pitch is changed by pressing on the neck in different places. Struck – Within the piano when a key is pressed a felt covered hammer hits one of the strings producing a sound. Bowed – This technique is used when the string is rubbed over and played using a box. Orchestral instruments –violin, viola, cello and double bass. Resonator – Strings are almost always joined unto this. A hollow structure usually made out of wood or metal. It amplifies the sound waves from the vibrating strings making the sound louder and fuller. Bow – This is a strong flexible stick with a ribbon of horse hair unto it. The hair is rubbed with resin that produces friction on the string.
