Fingering for 6-Hole Flutes
This discussion of fingerings for six-hole flutes proceeds stepwise through three levels of difficulty:
- fingering the main notes in the first two octaves
- fingering accidentals (sharps and flats) in the first two octaves, and
- fingering notes in the third octave.
In the fingering patterns shown below, "x" signifies a covered hole and "o" signifies an un-covered hole. The embouchure hole into which you blow is understood to be on the left and is not shown.
Main Notes in the First and Second Octaves
Fingering a six-hole flute is pretty straightforward if you stick to the notes corresponding to the key of the flute. A D flute should have the following fingering for these "main" notes in the first and second octaves:
D xxxxxx E xxxxxo F# xxxxoo G xxxooo A xxoooo B xooooo C# oooooo
In flutes of another key the same principle will apply – simply open the holes in progression to sound the main notes of the flute.
The difference between the first and second octaves, at least with respect to the main notes, is in how you blow the flute, not how you cover the holes. Practice with all holes open until you can blow two distinctly different notes an octave apart. Blowing the higher note will usually require that you blow harder. Rotating the embouchure hole toward you and away will help.
An alternative fingering for the lowest note in the second octave is as follows:
D oxxxxx
Accidentals in the First and Second Octaves
Playing accidentals like sharps and flats is a little less straight-forward for the following reasons:
(1) The best fingering can vary for different hole diameter patterns.
(2) Fingering needed in the second octave is usually different from the first.
One technique for sounding a note a half-tone lower than a given note, a C instead of a C# for instance, is to cover the hole only fractionally. If you slide your finger slowly over a hole you will discover that the tone of the note is lowered progressively. Considerable practice is required to get a reproducible result using this technique, but it is one approach. The technique is sometimes called "half-holing".
An alternative is to cover one or two or three or more holes below the highest open hole. This technique is sometimes called "forked fingering".
Progressively lower tones are commonly achieved as more holes are closed below an open hole. Experiment will tell you what pattern gives a good result for a particular flute - not all flutes behave the same when using this technique! Particularly, a large hole, perhaps 1/2" in diameter, will require more holes to be covered than a smaller hole if the objective is to lower the note a half tone.
On a D flute you can try the following experiment to discover how best to play a C in the first octave with forked fingering.
First, blow a C# (all holes open).
C# oooooo
and then, closing holes progressively, try the following patterns:
oxoooo
oxxooo
oxxxoo
oxxxxo
One of these latter patterns (usually oxxooo or oxxxoo) will tend to approximate a C. However, if you try to use the same fingering to get a C in the second octave it probably won't work (a higher note tends to result as harmonics kick in) and closing only a single hole (oxoooo) may be a better solution.
Similar experimentation will usually lead you to a pattern which will allow you to flat each of the highest three notes on a six-hole flute, at least in the first octave.
Experimental results for one flute are as follows:
first octave second octave C oxxooo oxoooo A# xoxxoo xoxooo G# xxoxxo ??????(I ran into harmonics which prevented fork-fingering a second-octave G# on this this flute.)
It's not usually practical to flat the lowest notes on a six-hole flute by the fork-fingering technique.
The Arcane Mysteries of Third-Octave Fingering
Most of the time a six-hole flute is considered to be a two-octave instrument. However, it is fairly easy to sound the lowest note in the third octave, and other notes in the third octave can usually also be produced. The fingerings required, however, have little relationship to those used in the first and second octave and depend strongly on facilitating harmonics. The following chart shows some third-octave fingerings that I scrounged from fingering charts for different sorts of flutes and tested more-or-less on flutes I've made. The fingerings for D, E and F# are the only ones I use much but the others seem to work when the wind is right and I'm feeling lucky.
D oxxoxx (best) or oxxxxx D# xxoxxx E xxooxx (best) or xxooox F xxxxxo F# xoxxox (best) or xxxxox G xoxoox (best) or xoxooo or ooxxxx G# ooxooo or ooxoo? A oxxxxx or oxxxxo A# xxooxx or ??? B xDoooo or xoxoxo
