Pianos can't be perfectly tuned - it's a mathematical fact!

When physicists talk about black holes they’re usually referring to highly theoretical objects – static, unchanging black holes viewed from “infinitely” far away. This makes everything clean and simple enough to attempt the already...

An orchestra fills an opera house with music, but a singer’s voice soars above the instruments. Its melody rings out across thousands of patrons— all without any assistance from a microphone. How is it possible that a single voice can be...

Pianos can't be perfectly tuned - it's a mathematical fact!

Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? What are the physics of music? In this episode of Crash Course...

In this video Paul Andersen explains how the wavelength of a standing wave is determined by the boundary length and frequency of the wave. The fundamental frequency has a wavelength double the boundary length. Harmonics are built on...

Stradivarius are synonymous with quality, but how we can replicate their sound is a mystery!

When a musical note is played, we hear the note intended - the fundamental - but also other tones called harmonics that are whole number multiples of the fundamental.

Different instruments can produce a wide variety of different sounds and notes, but why is this? Revealing how scientific principles combine to make music. Physics - Waves - Learning Points. Musical instruments are designed based on the...

Music is made by sound waves. The objects that make those waves make complex waves. Which create what we call Harmonics. Today we look at some Music Physics and get an intro to the Harmonic Series.

Did you know that all musical intervals can be expressed using some basic math? Today we talk about some of that math.

Since I released the Intro to the Harmonic Series video, I've gotten a lot of questions asking what you can do with it. So, I thought we might look at a practical application of it, Writing and Voicing Chords.

The one where we shine a laser at a speaker and see what happens. I was not prepared for all the weird stuff that happened! This experiment is based on a video by Steve Mould. Check out his video hereref='https://youtu.be/C-V1uXeyGmg'...

The equation for the harmonic frequencies of stringed instruments is derived. Harmonic numbers and fundamental frequency are defined. A guitar is used to demonstrate harmonic numbers.

The equations for the harmonic frequencies of open and closed pipe wind instruments are derived. An animation of a longitudinal standing wave pattern in a closed pipe is shown. Displacement and pressure nodes and antinodes are shown.

Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better...
