Observations on intonation.

Which flute is the hardest to play? Bass flute - no doubt about it.

Some of my own recordings. Some are solo, some are duets or trios with me playing all parts. It's not the best sound quality, but good enough for me to use it as a practice tool to listen for what I need to work on.
This section is periodically updated.

Albinoni, Adagio for Organ
I arranged this piece for a bass flute duet and recorded it on my H4 in stereo multitrack.

Kuhlau Op. 10
A duet transcribed for soprano & alto flute, recorded on my H4. This is recorded in stereo in my practice room about 7 feet from the flutes. The soprano (1st part) is right of center, alto is left. I played both parts and mixed them together.

Gary Shocker, Three Nuns in the Desert
Gary Shocker put this up on this web site as a free download and told everyone on the FLUTE list. So I gave it a try, soprano on part 1, bass on part 2, alto on part 3. It's strange and modern, none of the individual parts sounds like much when playing, but it gels with all 3 together.

Berbiguier Etude #1
For the past year or so I've been working through the set of 18, currently on etude #16. I might record them all - this is the first one in C major. They're all so tricky I can never play one perfectly - always seem to make at least 1 mistake...

Minuet from Haydn's Echo
A duet for 2 soprano flutes, recorded with my H4. Multitracked mono.

Round from Telemann's Sonata #2
A duet for 2 soprano flutes, recorded with my H4. Multitracked mono.

Something Christmasy
A theme & variations on a Christmas tune, for alto and soprano flute. Multitracked mono. Recorded with my VT-100 dynamic mic and sound board.

Kohler Duet part 1
The first part of a Kohler duet for two soprano flutes. Multitracked mono. Recorded with my VT-100 dynamic mic and sound board.

Bass flute stuff:
Here is what my Jupiter 523 sounded like:
Oboe solo from Bizet Symphony #1, movement 2
Suffice to say that bass flute has a complex sound that is hard to capture.
Here is what my Jupiter 1123SE sounds like:
The duck from Peter & The Wolf, normally played by the oboe.
and I like its tone better than any other bass flute I've played, especially its more powerful bottom octave. You can hear the difference in tone quality.

Comments on flute headjoints.

All of these flutes are in good playable condition. Some play better than others, as some are better instruments than others. I don't play the Artley or 3SB much because the 1011 is a better flute in every way. I keep the 3SB as a backup and the Artley mostly for nostalgic reasons.
