Here is a description of all the various sizes of recorder:
Contra Bass in F
Although we don't have one (still waiting for the
lottery win!), the Contra Bass will descend another
five notes beneath the great bass, to F. Being 6
feet tall, players usually stand to play the
contrabass (although they can sit with the folded
box-section instruments) As with the Great Bass,
the Contrabass has a noticeable delay between
blowing and speaking which the player needs to take
account for, along with a definite requirement for
more air. As with the other Bass instruments
keywork is essential on this large instrument.
Great Bass in C
This recorder is one octave lower than the tenor,
so its lowest note is C below middle C. Due to its
size there is a noticeable delay between blowing
and the recorder speaking, although not as
pronounced as on the Contrabass, players still have
to allow for this by playing slightly ahead of the
beat. Like the Bass in F, it always has some
keywork to assist fingering.
Bass in F
This instrument is one octave lower than the treble
and its lowest note, therefore, is the F below
middle C on the piano. It is the most powerful of
all the Bass instruments, and is the highest
pitched recorder playing from the bass clef. It
includes some keywork to help fingering the
increasingly large distances between holes.
Tenor in C
This is one octave lower than the descant and so
its lowest note is middle C. It has lovely rich,
mellow tones and can happily be a solo instrument.
It can have several keys to help play the lowest
notes.
Treble (Alto) in F
This recorder is often used as a solo instrument.
The lowest note of the treble is the F above middle
C, its range the same as the descant. It is the
biggest instrument not to commonly require any
keywork on the body.
Soprano (Descant) in C
The descant is the most well-known recorder, and is
the one most often used to teach children. The
lowest note of the descant recorder, that is the
note played when all the holes are covered, is the
C above the middle C on the piano. The range is two
and a half octaves.
Sopranino in F
The lowest note, that is the note played when all
the holes are covered, is the F an octave above the
middle C on the piano. The range is two and a half
octaves and is commonly used to add brilliance to
the overall sound.
Garklein-Flötlein in C
The smallest recorder with the longest name. The
lowest note, that is the note played when all the
holes are covered, is the C two octaves above the
middle C on the piano. The range is two octaves but
at the extreme it’s uncomfortable on the eardrums
of anyone standing close to you… Its best used for
solos or 'decoration' in full orchestration. This
recorder has a very prominent sound. As you can
imagine, some peoples' hands and fingers are just
too big to easily play this tiny instrument!
