Below are some charts to help you understand the scales that can be played on the different Fula flutes (also known as tambin). Each flute can play one complete diatonic scale. The flutes most commonly found (and the ones sold by Kassa Flute Co) are: A♭, G, G♭, and F. The A♭ flute is our smallest flute, with the F being the longest (and lowest).

Intervals between frequencies
An interval is the difference between two musical notes: the distance between two frequencies, often expressed in semitones (or cents). The below tool calculates the exact number of semitones between any two given frequencies, or, given a frequency and an interval, will calculate the note required to achieve that interval. Some facts: A semitone is equal to 100 cents. The twelve-tone equal temperament scale divides an octave into 12 semitones (of 100 cents each). A theoretical model of an equidistant heptatonic scale, where all the intervals of the seven-note scale were perfectly equal, would result in an interval of 1.714 semitones each.
Instrument builders and technicians often need to do calculations that require knowing the frequency and/or wavelength of certain notes. The following table shows the frequencies of all the notes of a standard piano, to a thousandth of a hertz. I generated this table using a script I wrote in PHP. I’ve also published the underlying PHP array as a Gist on GitHub, that is freely available for use in your own website or project. Get it here.
Musical Notes to Frequency Table
Recently, I came across the need to reference a chart of musical notes and their frequencies, for the purpose of calculating the wavelengths of certain notes, and realized there wasn’t a great tool out there to do this automatically. So, I created a multi-dimensional PHP array so that I could access this data, loop through it, and make whatever calculations I needed to. Below is the resulting Gist, and it is available to use freely in your own projects. I used this PHP array to generate a handy reference table of musical frequencies and wavelengths, available here.
