LAB#24SL:Musical Intervals

Objective:

To determine the frequency ratios for common musical intervals. Procedure:

Come into the lab, open DataStudio, switch on the interface, select Create Experiment, then Sound Creator. Change simultaneous tones to 2. Then put on the headphone to listen the voice, changing the wave of a sound to a longer wave(lower tones). Hum the indicated for a specified interval and find the pitch for the 2nd note. Do it for 5 times with 5 different songs.

Conclusion

In this lab, we know the wave of the songs concern with the tones of it. Shorter period waves have a lower tones. Amplitude cause the loudness of the songs. This lab is good for us to analyze the notes of all the songs.

LAB#24SL:Musical Intervals

Objective

To determine the frequency ratios for common musical intervals. Procedure

First, start Datastudio,choose Create Experiment, then Sound Creator. Then, Change simultaneous tones to 2. Next, put the headphone on and started to find our voice tones. Next, hum 5 songs in key:C,D,E,F,G. Finish the 5 songs and finally, record the data in calculation table.

Conclusion

This lab is about sounds. I am very appreciated that our school have these devices to let us to test voices by myself. To measure the sound of mine is difficult because when i was on the headphone, I couldn't hear my voice clearly. Finally I change the length of the voice on the computer to a high key then fix the problem.

LAB#24SL:Musical Intervals

Objective

To determine the frequency ratios for common musical intervals. Procedure

Enter the lab room and switch on the computer, then open the DataStudios and set up Create Experiment, Sound Creator, and change simultaneous Tab to 2 and choose Period view. Then change the Amplitude handle and wavelength to a perfect place. Then start to hum the songs that require, try to use some different key to measure what cause the sound changed. Finally, write down the data and clean the area.

Conclusion

During this lab, I found many things amazed me, such as the C key have a very similar but not exactly same wavelength with D key. I try moving the A wavelength to 2 times as B wave, but it make a strange noise. I need to
