|
| an art based on the organization of sounds in time |
|
| Four main properties of musical sounds |
|
| pitch, dynamics, tone color, and duration(length of time a musical sound lasts) |
|
|
|
| relative highness or lowness that we hear in a sound |
|
| Pitch of a sound is decided by the frequency(speed) of its vibrations |
|
| measured in cycles per second. The faster the vibrations the higher the pitch; the slower the lower the pitch |
|
| pitch and size of objects |
|
| smaller objects vibrate faster and have higher pitches: thus plucking a short string produces a higher pitch than plucking a long string |
|
|
|
| a sound that has a definite pitch |
|
|
|
| Two tones will sound different when they have different pitches. The distance in pitch between any two tones |
|
|
|
| When tones are separated by the interval called an octave they sound very much alike |
|
|
|
| 2:1 if say one is 440 cycles per second then the see tone an octave higher would be 880 cycles per second |
