Content Inside: Music Notation 2 - Music Notation 2 Music Fundamentals 14-119-T In the last lecture, we discovered the musical alphabet, and how a clef defines where a note is posi- tioned in the staff. More on the Octave: At this point, you are probably asking what the numbers after the note names indicate. These simply identify the octave of the note. Do you re- member what an octave is? To review, an octave is the interval, or distance between two notes, where of seven letter names [see figure1]. We can also explain this using basic acoustics, but this requires a little further explanation. You probably remember from your high school physics course that sound is simply oscillations in a sound medium. Sound can generally be described as waves of compression and rarefaction in the air. The more compressions and rarefactions, or cycles, that occur within a time period determine the pitch of the sound. For example, if a sound source, such as a vibrating string changing the air pressure, oscillates, or completes a cycle, at 440 times per second, the frequency is said to be 440 herz (Hz). 440Hz, in our musical system, happens to be the A above middle C (or A4), and is the pitch orchestras in the United States use to tune – it is also known as “concert A”. In Europe, their concert A is 441Hz. The difference between 440Hz and 441Hz is not recognizable to the normal ear unless you listen to the two simultaneously. I’m not sure why the Europeans use a different tuning scale, but it’s an interesting trivia fact you can use to impress people at your next cocktail party. If we have labeled A4 as 440Hz, then the next octave up, or A5, cycles 880 times per second (880 Hz). In other words, the ratio of two audio signals an octave apart is 2:1. With this knowledge, you can figure out what the frequency is for a pitch an octave lower than 261.6Hz (middle C). Ok, don’t get out your calculators. The answer is 130.8Hz (261.6 divided by 2). In the most common syste ...
