Transcript

  • 1. What is pitch? • In music the pitch of a sound means how high or low a note is. • Musical pitches are relative, any note is higher or lower than another. • It is the degree of relative highness or lowness of a sound
  • 2. Frequency affects PITCH• It is measured in a unit called Hertz and is determined by the sound’s frequency of vibration. ▫ The greater the frequency the higher pitched the sound will be. ▫ A note that is vibrating at 256 Hz will be caused by sound waves that vibrate at 256 times a second. This will be Middle C on the piano.
  • 3. Pitch Notation • Staff • Cleff • Notes
  • 4. Vocal Pitch• It mostly depends on the length and thickness of the vocal cords. ▫ Women tend to have higher voices than men because they have shorter vocal cords. ▫ Men tend to have lower voices than women because their vocal cords are longer and thicker.
  • 5. Vocal Pitch• The pitch of someones voice can also be affected by emotions, and moods. ▫ For example, being frightened or excited can make the pitch higher because the muscles around the larynx unconsciously contract.
  • 6. Definite pitched Instruments • A definite pitched instrument produces sounds at fixed frequencies. ▫ Example: when you press Middle C on the Keyboard of a piano the same tone occurs every time.
  • 7. Definite pitched Instruments • Other indefinite pitched instrument have no specific separation between notes. ▫ Example: the slide of trombones allows to play an infinite numbers of tones between Middle C and C sharp.
  • 8. Definite pitched Instruments • As it occurred with vocal cords: ▫ The shorter the strings or the air tunnels of the instruments, the higher pitch these instruments will play at. ▫ The longer the strings or the air tunnels of the instrument, the lower pitch these instruments will play at.
  • 9. Indefinite Pitch Instruments• Not all musical instruments give notes of a particular pitch. Many percussion instruments like drums, triangles and cymbals are instruments used for rhythms. ▫ This class of percussion instruments are named: unpitched percussion instruments
  • 10. Specific Vocabulary• Pitch: altura• Frequency: frecuencia• Vibration: vibración• Hertz: hercios• High: agudo• Low: grave• Definite pitch: altura determinada• Indefinite pitch: altura indeterminada• String: cuerda
  • 11. Useful structures• High pitch, very high pitch: • The violin plays at a high pitch, the violin is very high pitched and the viola is medium-high pitched… • Which is higher in pitch the violin or the viola? = Which is higher pitched the violin or the viola? • The violin is the highest in pitch string instrument • The violin is higher pitched than the viola • The viola is not as high pitched as the violin• Low pitch, very low pitch: • The double bass plays at a low pitch, the double bass is low pitched and the cello is medium-low pitched… • Which is lower in pitch the violin or the viola? = Which is lower pitched the violin or the viola? • The double bass is the lowest in pitch string instrument • The double bass is lower pitched than the cello • The cello is not as low pitched as the double bass
