Material Requirements: Varies by instrument chosen to build, Computer is required for documentation.

*If power tools are needed talk with parents first*

Start by opening the Spectrogram website and playing around. Document your findings here. (What is a Spectrogram? What can you do on the website?)

Next think of an instrument to build. Music and sound comes from waves. That is a very simple understatement, but I think you can figure out what will make a sound. (Like a rubber band or piece of metal) *Use the resources to the left for inspiration.

Finally build your instrument and record it on the Spectrogram. Take a screen shot add it to the google doc where you put your initial findings and write about what you noticed?

Now that you have an instrument how can you tell what type of sound its making using the spectrogram? How do we know when sound becomes music? What does music have the power to do?

Start by analyzing the sound you created. (if you want to change your instrument you can) What note, pitch or frequency is it?

Next turn your sound to music. Use Audacity (a free music editor to record) or use the Oscilloscope to loop and playback the sounds you created. (Chromebooks already have audacity installed) What is required for a sound to become a beat?

Then try to copy one of your favorite songs, with the instrument you made. You can do this by playing the song and recording with the oscilloscope, then dissecting the parts to see the time between the sounds.

Finally post your Song to google classroom.

Make an actual song and post it to google classroom.

Give feedback and likes to others students work.

Use these resources to better understand and refine your music.
