Following on from the previous quiz on Percussion Frequencies, we’re opening up a new quiz today: covering Frequency Bands and Harmonics.

Once you’ve got to grips with the starting material in the Frequency Fundamentals course, you should find you’re getting a good sense of where different frequencies lie in your hearing range. The second half of the course then introduces the 10 standard bands of frequencies used when analysing audio and making adjustments to the frequency balance:

If you’ve been working on the Frequency Fundamentals series here at EasyEarTraining.com, you may be looking for a way to practice the skills it teaches. Fotios has created a special quiz for the first half of the series, covering drums and cymbals.

The Frequency Fundamentals course takes you from the most basic concepts, through to a working knowledge of the 10 core frequency bands which cover the human hearing range. The following two articles use sounds from a standard drum kit to get you started listening for frequencies:

Up to this point in the series we’ve focused on characterising each sound with a single frequency representing its pitch. In today’s article we’ll consider the other frequencies present in musical sounds.

Compound frequencies, harmonics, blah blah blah!

Right?

No; actually in the real world, most sounds are made up of more than one frequency. We’ll forgo the actual full-on physics formula for sound creation, as that is way past our scope here…BUT…what IS of importance is that most sounds have a blend, or ratio, of multiple frequencies that resonate to create the sound that you hear. Hence the term ‘compound’ frequencies.

Harmonics

Now, speaking of this resonance business; all of the frequencies contained in a sound except for the main (’fundamental’ or ‘dominant’) frequency are called harmonics. Usually, they are found at precise multiples of the main frequency. The pattern is this: Click to read the rest…
