Chrome Music Lab: Instructions: ● If available, please access a laptop that has Google Chrome installed. ● Go to Chrome Music Lab at musiclab.chromeexperiments.com ● Select from the following activities: (Younger students will find ‘Song Maker’, ‘’, ‘Spectrogram’, and ‘Kandinsky’ the most intuitive and find the most success with those activities) ○ Song Maker ■ Make a tune by filling in rectangles. You can change the instrument that’s playing. You can also add a rhythmic section underneath. In the settings, you can change how long the song is, how many beats per bar, what type of scale you can use, and the range of the instruments. ○ Rhythm ■ Make a beat by filling in dots. Use the arrows to navigate different percussion ensembles. Each dot in the stack represents one of three different instruments. You can also pause the beat. ○ Spectrogram ■ A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time. You can click the microphone to record audio to see what the spectrogram of your voice will look like. You can also click and drag your finger to create sounds. You may click on the other icons to see what the spectrogram of certain instruments looks like. ○ Chords ■ Press the different keys on the keyboard (there are black and white keys). Change the slider between ‘Minor’ and ‘Major.’ See if you can figure out the difference in sound between a minor chord and a major chord. See if you can figure out the differences of highlighted notes between a minor chord and a major chord. ○ Sound Waves ■ See what sound waves look like when you play different notes. See what happens when you play low notes (to the left of the keyboard) and see what happens when you play high notes (to the right of the keyboard). You may click on the magnification to see a representation of a sound wave. ○ ■ See what arpeggios do in music. Select the pattern you want using the arrow keys. Select the chord you want from the wheel. The upper case letters represent major arpeggios while the lower case letters represent minor arpeggios. Once you are satisfied, press the play button. You can change the arpeggio while it’s playing. You can change the instrument in the lower left corner and change how fast the arpeggio plays in the bottom right corner. If you figure out the chords of your favorite song, see if you can sing along to it. ○ Kandinsky ■ Draw shapes and lines to play music. This works better if you draw smaller shapes and lines. Select your instrument by changing the color in the bottom left of the screen. Once you’ve drawn plenty of shapes, press the play button to hear your creation. ○ Melody Maker ■ Select one rectangle from each column to create your melody. Press the play button to hear it played back. Drag the slider to change how fast and slow your melody is played. Press the middle button to add an automatically generated harmony part to your melody. ○ Voice Spinner ■ Press the microphone to record a short snippet of your voice. Drag the slider to hear your voice played back in different ways. If the slider is to the right of the center, your voice plays forward. If the slider is to the left of the center, your voice plays backward. ○ Harmonics ■ Click and hold each wave pattern to see what each harmonic looks like. The one on the left is the lowest and slowest moving wave, while the one on the right is the highest and fastest moving wave. ○ Piano Roll ■ Use the arrows to navigate to different pieces of music. Press the play button to hear them. There are 3 possible sounds. The left button is a piano. The middle button is a synth. For the right button, you record your voice, and the sounds of the piece are now your voice. ○ Oscillators ■ Use the arrow keys to navigate through different wave types. Drag each wave type to see what kind of sounds are generated. Dragging the oscillator upwards raises the pitch while dragging the oscillator downwards lowers the pitch.

○ Strings ■ Press each string in different locations to see how low and high they are. The longer the string, the lower the pitch, and the shorter the string, the higher the pitch. You’ll see that the strings are divided up into fractions. See if you can discover how the ratio of sizes affects the pitch.
