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

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

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...

Howcast - Let musician Alex Skolnick teach you how to play natural harmonics on guitar in this heavy metal guitar lesson from Howcast.

Howcast - Learn how to use an electric tuner in this Howcast video about how to play a pedal steel guitar.

Join us and learn how to harmonize a melody using the natural minor. We start by constructing the scale and the chords in D natural minor, before going on to observe the harmonization of a melody in D natural minor. We consider the...

How fractions are used in music – and Pythagoras built a whole musical scale based on fractions! Maths - Number A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts...

Discover three harmonic surprises that occur in Mariah Carey’s famous Christmas hit, “All I want for Christmas is you”. Many song composers find themselves using familiar and predictable chord patterns, and they would love to discover...

This is a Short Answer question but is not included in either AP Physics C curricula.

This problem is about determining the period of oscillation when given the equation for an object in simple harmonic motion.

These are my solutions to the Multiple Choice section of the Mechanics portion of the 1998 AP Physics C released exam. AP® is a registered trademark of the College Board, which was not involved in the production of, and does not...

Review of the Mechanical Waves topics covered in the AP Physics 1 curriculum.

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.

Review of the Simple Harmonic Motion topics covered in the AP Physics 1 curriculum.

Here I describe the main formulas used for harmonic excitation.

There are 3 minor scales, or more precisely, 3 variants of the minor scale because of how harmony and melody interact in Western musical tradition. Why do they exist and what are they? In this music theory lesson we explain the Natural...

Two blocks oscillating via springs is a 2 DOF system. The final solution will have the form of a



a modal vector times cos(w1t - phi1) + another modal vector times cos(w

2t -phi2).

The system is hence said to be...

Calculus based review of Simple Harmonic Motion (SHM). SHM is defined. A horizontal mass-spring system is analyzed and proven to be in SHM and it’s period is derived. The difference between frequency and angular frequency is shown. The...

Showing you how to begin a composition using the whole tone scale. The two transpositions of the whole tone scale are explained and consideration is given to how the scale can be used as the basis for melodic and harmonic construction....

Proof of the steady state amplitude and phase for a spring mass damper system with an harmonic load acting on it.



Once you get good at it, you don't need to recreate another z equation like I've done. You can just solve as if...

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.
