1. Concept
My idea is to create a simple music instrument installation using Max/Msp. At the end we should be able to play music with the laptop keyboard, just like the application "Garage Band" or piano app on mobile phones.
The main function I would use is the sequencer we learned at the beginning in class. I would also find the chart that compares tunes with frequency of sound to make a complete scale of music.
2. Chart: Comparison of tunes and frequency/Hz
Middle tone 1 - 523
Middle tone 1# - 554
Middle tone 2 - 587
Middle tone 2# - 622
Middle tone 3 - 659
Middle tone 4 - 698
Middle tone 4# - 740
Middle tone 5 - 784
Middle tone 5# - 831
Middle tone 6 - 880
Middle tone 6# - 932
Middle tone 7 - 988
High tone 1 - 1046
3. First try: build the keyboard and try to play a simple song
So I built a keyboard according to the frequency of central c to high c. And i tried to play the "Ode To Joy" with it. I also recorded the song and the whole scale of all tones.
Here are some problems I found:
1\ The keyboard cannot be played very fluently. it may result from the delay of a single note.
2\ the music keyboard is unlikely to range widely due to the keyboard of laptop has limited letters.
Next i will try to solve the first problem and continue to relate this keyboard to Arduino led lights.
