1. All sounds are produced from AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION .

2. The number of complete vibrations which a guitar string makes in one second is called the AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION and is measured in AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION .

3. A AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION note has a higher AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION than a low pitch note.

4. The pitch of a note made by a stretched string can be raised by increasing the AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION of the string.

5. AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION are caused by reflected sound waves.

6. The speed of sound in AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION is greater than it is in air.

7. If the length of a stretched, vibrating string is shortened, the pitch of the note it produces is AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION .

8. If two stretched strings with the same length and tension are vibrating, the thicker string will have a AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION pitch compared to the thinner string.

9. If you blow over a tube that is partly filled with water then the pitch of the note will rise if the water level is AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION .

10. The higher the frequency, the greater the number of AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION per second.

11. The thick strings on a guitar will produce a AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION pitch note compared to the thin strings when they both vibrate.

12. The short strings in a harp will produce a AIR RAISED HIGH PITCH LOW WATER FREQUENCY SPEED LIGHT HERTZ ECHOES VIBRATIONS VIBRATE LOWERED TENSION pitch note compared to the long strings when they both vibrate.
