Supercorder!
2-1/2 Octave Fully Keyed Alto Recorder
with Strong Sound and In-Tune Dynamic Range

(...just seven keys, no complex linkages!)
Dual B, Bb key (R. index), R.H. keys to change E to Eb
& D to Db (R. 2nd & 3rd), lowest F & F#
keys (R. 4th), lowest G & E keys (L. 4th)
Note: Traditionally alto recorder is pitched in F but played
with untransposed music.
In the transposed terms of most wind instruments these
keys translate to:
Dual F#, F key (R. index), R.H. keys to change B to Bb
& A to Ab (R. 2nd & 3rd), lowest C & C# keys
(R. 4th), lowest D & B keys (L. 4th)
Latest version with more flexible right hand "thumb guide"
feature instead of abrupt "thumb rest" is shown.

Supercorder evolved from 5 keys to 7, making better Eb &
Db played by adding middle right hand fingers to E & D.
I also did a sideline two-key "Modern Alto" version.
Note, April 13th, 2025:
The Supercorder,
which I created and developed in 2003-2007, is too fabulous an
instrument to be lost into forgotten history. People love the
sound and I've played it in amateur concert bands and orchestras*,
often in place of oboe when there wasn't one, sometimes flute.
Usually without amplification as the sound is quite strong. An
oboe player claimed it was louder than her oboe. This is an
exaggeration.
Given the opportunity lots of musicians would delight
to play a supercorder, so for an ambitious craftsman there's a
unique opportunity to make a career or business out of making
them. And then composers will start putting them into their
scores. I was no craftsman when I started. It came with effort and
practice.
I have been meaning for some years to create a new
website about the Supercorder after the private website where it
was originally hosted (saers.com) was completely changed for the
owner's evolving purposes and most of the content including mine
deleted. But in the press of newer things, I seem to never get
around to it. It now occurs to me to start simply by heavily
editing and reposting this original web page rather than trying to
make a new one from scratch.
I've removed sales info and so on as I no longer make
them. (I made about 20. Thefts of special tools and wood in 2007
caused a break, and I was already into other things.) I'm deleting
most of the info about 2 and 5 key versions as the full 7 key is
"the real thing". Many of the links won't be active immediately.
For example I plan to post the video files to
CraigCarmichael.substack.com and link to there. And I'll have to
hunt down most of the sound files from the old hard drive. I plan
to write more about constructing them, with dimensions of the bore
reamers and hole guide. I hope to add individual updates and links
as I find the time.
* I've been asked, "Why only amateur
groups? Wouldn't playing a Pro group better highlight the
instrument?" I have played several instruments but I am not a pro
or virtuoso player of any, even my own. And of course a
professional group would rarely permit a substitute instrument.
Introduction
Supercorder
is a new design of F-alto recorder with exceptionally strong and
even sound power throughout all the notes of its extended chromatic
range.
It is made easier to play by the Bb-B
key* for the right index finger alone* that
replaces these two worst forked fingerings with strong, well tuned
tones and simplifies note sequences in every key. The finger covers
the hole lightly for B and, without any other movement, presses down
to also close the key for Bb and notes below.
Other keys (F-F# and E-G) on the two fourth fingers make the entire
extended low range strong and even, with simple note transitions for
all chromatics. A third pair of ring keys on the fully keyed model
employs the middle right hand fingers to eliminate the last weaker
'forked' fingerings, C# and Eb. All the notes from G# up to E
can be fingered the same in both octaves.
The pitch control hole
covered by the player's sensitive lower lip provides the tune-by-ear
finer pitch control of most modern wind instruments for flexible
dynamic range and a lovely, expressive vibrato.
The voicing changer
lever, operated by a slight twist of the playing position, makes low
notes and lower forked notes more stable and stronger. It can also
be used to flatten the pitch to eliminate sharpness when blowing
quite loudly. The effect is akin to shading the window with the
hand.
The Baroque Supercorder
recorder is (was) a Baroque fingered F-alto recorder, equivalent to
other 'modern' long-bore recorders but with the additional Supercorder
features other than keys: the adjustable
porcelain mouthpiece with a wider, smoother
windway, built in thumbrest,
pitch control hole and voicing adjuster lever.
* "Today I tried the new type of key for the
B and B flat ~ invented by Craig Carmichael ~ on the Tarasov
alto. I was really impressed by the ease and stability with
which it works. A simple idea that really improves the sound
as well. It gives the development of the "21st century"
recorder many new possibilities."

Supercorder General Advantages |
Designed for Strong Sound with a wide crescent
windway of smooth porcelain and a deep window, and a
"modern" long bore profile |
Strong, Best Tuned Notes and Easier Fingerings with
Keys:
* low F# & G with the F/F# key pair
* B & Bb (both octaves) with index-finger-alone
B-Bb key
* low E, G# & A with G/E key pair
* C# & D# (Db & Eb) with Db/Eb
key pair
The 7-key "fully keyed" Supercorder replaces All
weaker forked fingerings with strong, well-tuned notes.
|
Smooth, easy fine-tuning, in-tune dynamics p to
ƒ, and lovely pitch-vibrato with natural-feel
tuning-vibrato port, activated by lip |
Voicing Adjuster improves playability and strength
of lowest notes |
Hygenic, non-allergenic porcelain mouthpieces that
can be replaced |
Near 3-octaves practical pitch range (extremes: low
Eb to sopranino high G, chromatic: 41 notes, or 3
octaves and a major third.) (I've found that I can get a
weak low D instead of Ebby sticking a little brass
tube in the Eb tone hole. That's as low as a voice
flute! |
Built-in thumbrest (wood turning) |
Hard Case included, to keep a fine, keyed
instrument safe |
There's more to a Supercorder than a typical alto recorder. It
does more, but if you don't like the sounds of the items in the
table below, perhaps Supercorder isn't for you:
Supercorder Feature |
Player Attention |
Three screws under the porcelain beak adjust the windway
position. Since the player is able to replace mouthpieces
and adjust the windway position for best sound, there is
no need to send the instrument out for revoicing. |
Player should be prepared to adjust the screws when
necessary with a small screwdriver and check the sound,
and repeat, until good sound and response is obtained. |
Except for the Baroque model (Baroque fingered), there
are new (mostly easier) fingerings with stronger,
optimally tuned notes. |
Except on the Baroque model, new fingerings must be
learned. |
The fine-tuning port allows play-by-ear tuning as is
common with most woodwind instruments, a lovely
pitch-vibrato, and fade-out end notes without drop of
pitch. |
Learning new lip-tuning technique and to adjust tuning
at different dynamics. |
Supercorders are a unique new type of instrument. As
such, they are hand-made and smaller details are still
evolving. |
Until such a time as production becomes more
standardized, players should be prepared to see some
variation between units, and parts that may sometimes look
a bit "homemade". (Ask for photos of a unit to be emailed
to you if desired before ordering.) |
7-key Fully Keyed Supercorder
replaces all weaker forked fingerings with easier keyed
fingerings via two ring keys. Eb is the same as E but
with right-hand 2 also pressed, and Db is as D but with
right-hand 3, the same in both octaves. F#2, which is hard to
get in tune on most recorders, is played well tuned as o
xoo oxoo. Normal lowest note is E, with a weaker Eb
available by bell-stopping. Some very high note fingerings
change, but more 3rd octave notes are added: E as / xxo
xxoo is sharp and an alternate is preferred (/ xox xxoo or
/ xoo oooo), high F is played / xox xoxo, and third octave A (/
xoo oxxo) is often a bit sharp unless 2 is part-holed (/ x/o
oxxo). For C and D, the keys are no help though arguably D, E
and perhaps F are marginally stronger, but when Eb or Db
is wanted, they're worth their more than their weight in
nickel-silver, if not gold. Have you ever thought of middle F as
a weak note? Well, now all the nearby notes are at least as
loud!

Playing Supercorder
Supercorder has a few fingering
differences, mostly easier, with its keys on 3 fingers. All
chromatic notes up to and beyond C4 (in fact, to G4 - same as
sopranino - is usual) are available, without bell stopping.
Second octave B to C# becomes a single finger transition. Many
notes are stronger and better tuned. (Low Eb1 is
available by fingering low-E and bell-stopping.)
The expressive vibrato and the ability to play
softly in-tune are easily practiced. For vibrato, the flute is
essentially 'shaken' up and down, making held notes attractive.
The player will also soon notice that low notes are less "fragile"
- they can be tongued more sharply and blown hard with good tone
and without overblowing.
Supercorder Fingerings
SYMBOLS USED
o = open hole or key
x = closed hole or key
/ = part-holed (usually thumb)
* = closed, open or part-holed: sometimes little difference, or one
may work or be tuned best.
4th left finger ("8"): e = e & g key pressed (straight finger);
g = g key pressed (curved finger); If "e" key is closed, "g" key is
also closed.
1st right finger: b: B "pipe" tonehole lightly covered; x: press
harder to close Bb key as well
4th right finger: f: F# key pressed (straight finger); x: both keys
pressed (curved finger); If "f" key is closed, "f#" key is also
closed.

These fingerings do not entirely exhaust the possibilities.
While the notes are fairly strong and even, there are a few
combinations by covering low right hand holes which further increase
the volume of some for when maximum output is wanted. (I often used
them in concert band on held notes.)
