MUSIC MID-TERM EXAM REVIEW… Sound - begins with the vibrations of an object, such as a table that is pounded or a string that is plucked. -it is transmitted to our ears by a medium , which is usually air. -as a result of the vibrations, our eardrums vibrate too and impulses are transmitted to the brain (where they are selected, organized, and interpreted) Music- an art based on the organization of sounds in time. -four main properties of musical sound #1. Pitch #2. Dynamics #3. Tone Color #4. Duration Pitch… highness or lowness of sound -pitch of a sound is decided by the frequency of its vibrations (speed , which is measured in cycles per second) *faster the vibrations, the higher the pitch *slower the vibrations, the lower the pitch *smaller objects vibrate faster and have higher pitches (ex: plucking a

short string produces a higher pitch than plucking a long string) Tone -a sound that has a definite pitch, vibrations of tone are regular and reach the ear at equal time intervals. * two tones will sound different when they have different pitches Interval- the distance, in a pitch, between any two tones -when tones are separated by the interval called an Octave they sound very alike. ( Octave- the interval between the first and last tones in the familiar scale.) do re mi fa sol la ti do- group of seven tones (produced by white keys of a piano) was the basis of western music for centuries. Then five more pitches were added (the black keys of a piano). Range or Pitch Range- the distance between the lowest and highest tones that a voice or an instrument can produce. Untrained voice- 1 ½ octaves Piano’s range- more than 7 octaves *the organization of pitch is a composer’s first resource.

•when instruments are played more loudly or more softly, or when there is a change in how many instruments are heard, a dynamic change results. •such a change may be made either gradually or suddenly. • a gradual change increase in loudness often creates excitement, particularly when the pitch rises too. •on the contrary, a gradual decrease in loudness can convey a sense of calm. Accent- a performer can emphasize a tone by playing it more loudly than the tones around it, this is called an accent. Terms pertaining to dynamics… Pianissimo… very soft Piano… soft Mezzo Piano… moderately soft Mezzo Forte… moderately loud Forte… loud Fortissimo… very loud Descrescendo… gradually softer Diminuendo… gradually softer Crescendo… gradually louder *all relative to what you are comparing it to Tone Color… the quality that distinguishes instruments
