Giving back to Guinée

Dave KobrenskiMar 8

More than a decade ago while traveling in West Africa, I began my apprenticeship with a master flute-maker from the Malinké tradition. My studies of this simple but powerful flute, and my continued relationship with the people of Guinée, have been one of the most rewarding (and sometimes challenging!) endeavors of my life. Over the years since, I have sought to continuously refine and improve the flutes that I make, and honor the tradition from which it comes — traveling back to Guinée whenever possible to work with and support my wonderful teachers there. It is with a lot of pride that I can say that the new flutes coming from the Kassa workshop are the best I have ever produced, and I’m pleased to continue my work in promoting the music and culture of Guinée! That said, back home here in the United States (or Europe, Australia, etc), it is all-too easy to overlook the poverty and suffering that the people of Guinée must endure every day. This is the daily reality for my teachers and their families, especially in Conakry. It is for that reason that I have decided to donate a portion of every flute sale to help support my friends and teachers there. You’ll notice that the prices of my flutes have increased a little, and this is to accommodate the increased time and materials in producing these flutes — but more importantly, to allow me to take 15% of every flute sale and use it for aid and projects in the communities where I have traveled and learned so much. Over the coming months, you’ll see more information and resources here on the Kassa Flute Co. website that will document how this money is being used, and I hope, over time, to include photos from my travels that show the connection between the Kassa Flute Co. and Guinée. The Kassa Flute Co. is a small operation, and a labor of love for me. But it has always been my hope to be able to use it to offer support, however small, to my friends and family in Guinée…and your support and continued patronage will help me with that goal. If you have any questions or thoughts, please don’t hesitate to contact us. I look forward to continuing to grow Kassa and to provide you with resources, information, and inspiration, while helping communities in need. — Dave Kobrenski

Semitone Interval Calculator

Intervals between frequencies

Dave KobrenskiReference-Charts, Flute-Making-Tools Jun 17 2018

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.

Dave KobrenskiReviews May 21 2018

At the Kassa Flute Co., we’re always delighted to hear about our customers experiences receiving their custom Fula flutes. Recently, musician / recording artist and ethnomusicologist William Johnson shared his own experience receiving one of our custom flutes — this one a traditionally tuned A♭ flute that we custom made for William recently. Says William: “I received the flute last week and let me tell you… this thing is GORGEOUS! Absolutely beautiful….Thanks again for your incredible work and speedy yet flawless craftsmanship, packing and shipping!” Below is the video that William created, sharing his experience receiving (and playing for the first time) his new flute:

Fula Flute Repair:

Fixing a loose embouchure

Dave KobrenskiFlute-Making-Tools Dec 15 2016

Fula flutes are fragile instruments, and are susceptible both to impact (dropping, being sat on etc) as well as to changes in temperature and humidity. In particular, cold weather can cause troubles with your Fula flute. While wooden flutes are more fragile than the rigid “pipe” flutes that we make here at the Kassa Flute Co, the embouchure (mouthpiece or headpiece) of any Fula flute is made out of beeswax and can become brittle in cold weather. This can cause it to become loose. In extreme hot weather, the beeswax can melt and cause it to become mishapen. In either one of these cases, the problem is not severe, and can be fixed relatively easy. In this short article, we’ll show you how to fix a headpiece that has become loose.

Toneholes and Tradition

How a 40,000 year old flute leveled the playing field

Dave KobrenskiArticles, Anthropology Apr 7 2016

Sometime between 40,000 and 45,000 years ago, a group of early humans on a migration route out of Africa, along the corridor of the Danube River valley, carried with them a small but significant object: a flute. Carved from the bone of a griffon vulture, with…

Flute Calculations Tool

for a Three-hole Fulani flute

Dave KobrenskiFlute-Making-Tools, Articles Jun 19 2015

The most common question I get about making flutes is, “How do you know where to drill the finger holes?” Here is the “electronic worksheet” along with tools and charts I’ve developed over the course of my flute-making journey, to aid in the calculation of tonehole placement for a 3-hole Fulani Flute made from uniform diameter tube.

Frequencies & Wavelengths of Musical Notes

Reference Chart

Dave KobrenskiResources, Reference-Charts Mar 17 2015

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.

PHP Array of Musical Frequencies

Musical Notes to Frequency Table

Dave KobrenskiResources, Reference-Charts Mar 16 2015

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. More info about the topic of Musical Frequencies at this Wikipedia entry.
