The Math and Science that MUSIC Brings!

PNA Band performs at the SCIENCE PARTY!On April 19th the PNA Band performed at the Science Party! So what does music have to do with science? First of all, ask yourself "What is sound?" Sound is vibrations that travel through the air. Sound is produced by continuous and regular vibrations, as opposed to noise. Sound energy travels in waves and is measured in frequency and amplitude. The energy in a sound wave can be measured using Decibels. The Decibel Meter shows examples of things that make noise and measurements in decibels. Amplitude measures how forceful the wave is. Your ear can only handle so many decibels. A normal conversation is usually at 60dB. Continuous exposure to sounds at 85dB can cause permanent damage. The band played a few numbers that demonstrated harmony. Harmony is more than just a pretty sound. Harmony consists of the notes or chords played along with the melody. Harmony adds feeling to the melody. ... One of the most basic harmonies in music is called the major triad. The major triad is formed by playing the first, third and fifth notes of the major scale simultaneously. In a Major Triad the 3 notes, or pitches are at a perfect 3rd and 5th distance apart from the root note, and the sound is pleasing. In a Minor Triad, the third note is lowered a half step and the sound tends to be interpreted to be a little sad to the ear. When notes that aren't the correct distance apart, are played together, they can be displeasing to the ear. BOOMWHAKERS!!!If you've ever been in the music room you would have seen these brightly colored plastic tubes. These tubes are called Boomwhackers! They are different colors and shapes. The size or length of the boomwhacker affects the pitch. A longer boomwhacker will have a lower sound compared to a shorter one. The color of the boomwhacker simply helps tell you which one to play. Color identification is easy for Kindergarten. Kindergarten has been exploring with melodies and simple rhythms by using these fun instruments. They get their name because you get to "whack" them on the floor!
Students are not expected to be perfect. This is a time for exploration and fun with music! Sure, we miss some notes here and there, but the giggles that come from the effort to play the songs is PRICELESS!
