Some percussion instruments have a definite high or low pitch, and some do not have a definite pitch. The bass drum, snare drum, triangle, cymbals, and tambourine do not have a definate pitch.

Indefinite Pitch Instruments: Percussion instruments that produce tones that are not precise pitches (cannot play an exact pitch or tune), such as bass drum, snare drum, cymbals, triangle, tambourine, etc. are called indefinite pitch instruments.

The pitched bass drum, generally used in marching bands and drum corps, is tuned to a specific pitch and is usually played in a set of three to six drums….Bass drum.

Mallets – A stick with a special tip used to create different sounds and feels on drums and cymbals. Mallets can have fabric tips, rubber tips, plastic tips, or wood tips, and create unique sounds on the drum set. Mallets are usually used for creating cymbal rolls and gong hits; however you can use them anywhere.

beater – a drumstick (usually with a mallet-type head) that beats a drum. Also, the rod and ball mechanism on a bass drum foot pedal is called a beater.

or bang the drum for. phrase. If someone beats the drum or bangs the drum for something, they support it strongly.

A set of wires (called snares) is stretched across a drum head at the bottom of the drum. The vibration of the bottom drum head against the snares produces the drum’s characteristic “cracking” tone. Claps, snares, and other “sharp” or “bright” sounds are often used in similar ways in drum patterns.

References of drums in the exodus The use of the timbrel or drum in this commandment is clearly defined as an instrument used for celebration which helps express joy and liveliness.

If the air is an object then no, you can’t produce sound without a vibrating “object”, but if the air is not an “object” then yes you can produce sound without a vibrating object. If an object moves through air faster than the speed of sound, then shock waves in the form of sonic boom is created.

Sound waves are formed when a vibrating object causes the surrounding medium to vibrate. A medium is a material (solid, liquid or gas) which a wave travels through. As sound waves move through a medium the particles vibrate forwards and backwards. So the nearer you are to a sound the louder it sounds to us.

The sound vibrations cause the plate to vibrate at the same frequency, which causes movement of the sand particles to form patterns of the sound generated. Sound vibrations can come in contact physically through the body and have an effect on our consciousness at the mental, emotional and spiritual levels.

The vibrating prongs cause vibrations in the air and these vibrations are transferred through air molecules which we are able to hear. When the vibrating fork is held close to the surface of water, the water’s surface also vibrates and ripples appear.

Answer. By sticking the vibrating tuning fork in a denser medium like water, the tuning fork’s energy is transferred into the act of splashing water, rather than hearing sound. Waves are energy carriers. The splash pattern in water is similar to what happens in the air with sound bouncing off in all directions.

The smaller a tine, the less distance it has to move, and the faster it will be able to vibrate. It’s the same principle as strings on a guitar. Without much room to wobble, a tight string vibrates quickly. A loose string, on the other hand, takes longer to shudder back and forth, resulting in a lower tone.

You can make very loud sounds with a drum, by hitting it very hard. When you hit the drum, the skin on top vibrates up and down. The harder you hit it, the bigger the vibrations and louder the sound.

Bigger vibrations make louder sounds, and smaller vibrations make quieter sounds.

You can manipulate the pitch of a drum in three ways: 1) tighten the drum’s skin to make the pitch higher; 2) put a thicker skin on the drum to lower the pitch; and 3) strike the drum closer to the center to produce a slower vibration and lower pitch, which sounds more resonant.

Sound vibrations, then, travel outwards in all directions in waves from a sound source. As they travel outwards the energy they contain becomes dissipated and therefore the sound becomes weaker the further it is from the source. The shape of a sound wave with no obstacles in its way would be approximately spherical.
