March 14 — 3/14, a date celebrated the world over as "Pi Day," after the irrational number. This year, to celebrate, musician Michael John Blake had the idea to compose, record and put on YouTube a musical interpretation of the most famous mathematical constant. He decided the song would be in C, then assigned each note a number: C=1, D=2 and so on up through 9. Using those assignments, he played the sequence of pi: 3.14159 through 31 decimal places. He assigned numbers to chords, too, but could only play the chords every other note and still make it sound vaguely musical. Finally, he used pi as the basis for the tempo — it's 157 beats per minute, which is half of 314. He played this part on several instruments, and layered them to make a song. The result isn't exactly catchy, but it's certainly melodic."It's random enough to where it's kind of odd, but then, because it's all based in the major scale, it musically works out to where it's sort of pleasing to the ear," Blake says. "For me, it has this great combination of pleasant but also slightly weird — kind of haunting."

I don’t know whether this melody can be assigned to classical music. But I think this is an interesting way to compose new music and an effective way to teach math. It is a good news for musicians and math teachers. Pi is the most recognized mathematical constant in the world. Scholars often consider Pi the most important and intriguing number in all of mathematics. The video posted by Michael on Yutube is very hot recently. This event tell us that music and math is linked in some way. We can express math using sounds. As a musician candidate, I think this is a wonderfully educational tool that is easily explained to young students of both math and music. PI, I'm sure, could also be incorporated into the rhythm pattern as well as inventing a completely new musical form to create a cohesive PI related musical and mathematical work. However, this is very aesthetically pleasing to the ear, and wonderfully visual at the same time. There is so many interesting mathematical constant in math, in future, you can compose a wonderful melody using anther constant.

At the end of this text, I give link about this popular music, if the reader is interested in the melody, you can listen online.
