Starting at any note the frequency to other notes may be calculated from its frequency by: Freq = note x 2 N/12, where N is the number of notes away from the starting note. Here is a table giving the frequencies in Hz of musical pitches, covering the full range of all normal musical instruments I know of and then some. It uses an even tempered scale with A = 440 Hz. The sample will comprise a short sequence of 5 chords, each comprising 3 or 4 different musical notes played concurrently. (Such notes are called "concordant" in music.)

N may be positive, negative or zero.



It has frequency 220 Hz.2.

It has a frequency of 440 Hz, and is one octave above the first A. Bass strings are (5th string) B0=30.87Hz, (4th string) E1=41.20Hz, A1=55Hz, D2=73.42Hz, G2=98Hz It can also play the notes, so is useful as a tuning note reference. … The frequencies 440Hz and 880Hz both correspond to the musical note A, but one octave apart. In this exercise you are required to use spectral analysis techniques to determine the musical notes played within a short audio sample (with sampling frequency 44.1KHz). It works on Windows and Linux. After long time of experimenting, people find that they tend to think a musical interval extremely harmonic if it consists of such two notes that the frequency of one of them doubles that of the other.

Frequencies of Notes on a Piano: Learning object Applet Description.

Now, let’s think about a musical interval.


It uses an even tempered scale with A = 440 Hz. In this video we will use the function we made in part 1 and generate an array of objects, containing note name and frequency of all notes within a specified range. Here's a light-hearted introduction to the concepts of trigonometric graphs. Thanks for reading my 71st article in the series 100-day music blogging challenge. Cello strings are C2=65.41Hz, G2=98Hz, D3=146.8Hz, A3=220Hz

In the western musical scale, there are 12 notes in every octave.

Next read the descriptions (below the graph) for the notes that sound "nice" with A (that is C#, and E). These are simple multiples of the fundamental frequency.

As the frequency goes up, the wavelength goes down.The time taken for each wave to pass our ear for A-220 is `1/220` second = `0.004545\ s`. Instead of calling out frequencies of musical notes, we refer to them using English alphabets.

Playing notes may not work on Safari on the Mac, though Firefox or Chrome on the Mac is ok. Note Frequencies.

(Such notes are called "discordant" in music. Not how there are 2 wavelengths for A-440 in the space of one length of A-220.4.

The octave number is in the left column so to find the frequency of middle C which is C4, look down the "C" column til you get to the "4" row : so middle C is 261.6 Hz. Also we call middle C "C4" : this is the commonest octave numbering but some people call middle C "C3" or even "C5". Bear in mind that everything here is in relation to the even tempered (aka equal tempered) scale, where an octave is a frequency ratio of exactly two and a semitone is a frequency ratio of exactly the twelfth root of two. Musical Notes.

In the real world however many different temperaments may be used - see

At this stage, a musical interval can be defined as an unordered pair of notes. Now, play the higher A.


physics frequencies musical-notes Instrument builders and technicians often need to do calculations that require knowing the frequency and/or wavelength of certain notes. Musical scale. Here is a table giving the frequencies in Hz of musical pitches, covering the full range of all normal musical instruments I know of and then some.

The next higher A in the musical scale would have the frequency 1760Hz, twice 880Hz.

Now, the question is: What are the musical notes? See what it says in the description for the "not-so-nice" notes.

This is what 1 unit represents on the 1.

This is a practical example of the graphs we learned about in In the learning object below, there is a piano which you can play (one note at a time). Tuning Frequencies for equal-tempered scale, A 4 = 432 Hz Other tuning choices, A 4 = This musician's use of a logarithmic musical scale reminds me of my own 10-tone scale that I used to compose music some years ago.

Stay tuned to find the answer in my next blogpost. )NOTE: The lower sounds may not play so well on a mobile phone speaker (if so, use earphones).See the background to the above learning object in:This trigonometry solver can solve a wide range of math problems.I have always been interested in the close connection between math and music.

As you play each new note, you'll see a graph demonstrating the frequency of that note.

Next, play some of the notes near to that A and notice how the graph changes as the frequency changes.3. A musical octave spans a factor of two in frequency and there are twelve notes per octave. For example, starting at D (146.84 Hz), the frequency to the …
