JI version of "quartive" based scale

Hello all,
For anyone who is interested, here is a JI version of the "quartive"
based scale I mentioned a few weeks ago(two-octave frame, 17 steps):

1, 12/11, 7/6, 14/11, 25/18, 3/2, 18/11, 7/4, 21/11, 25/12, 9/4,
27/11, 21/8, 63/22, 25/8, 27/8, 81/22, 4

or looked at another way:

12/11, 77/72, 12/11, 275/252, 27/25, 12/11, 77/72, 12/11, 275/252,
27/25, 12/11, 77/72, 12/11, 275/252, 27/25, 12/11, 88/81.

I've had the opportunity to listen to some pleasant melodies in it
using the tunable bells but haven't heard any of its harmonies yet.
I'm particularly anxious to hear the 4-6-7-9 chord.

Cheers
Eric deLaubenfels

Hi, Eric! Where can we hear this?

Hi, Bob
Although my cousin urges me to buy a synthesizer, I don't have one
yet. But on John Starrett's excellent website under musical examples
I found the tunable bells applet. From the frequencies listed below I
chose 8 at a time and set modes to 2 and began plinking away.

82.407, 89.899, 96.142, 104.882, 114.454, 123.611, 134.848, 144.212,
157.322, 171.681, 185.416, 202.272, 216.318, 235.984, 257.522,
278.124, 303.408, 329.628

You can also multiply or divide any of these frequencies by 4. I
copied the convention used for the BP scale where BP A1 = E = 82.407
Hz. BTW, can anyone here tell me how the BP pitch correlation to
12tET was chosen? I asked Charles Carpenter this question and he
thought that it was an arbitary choice. Even if it was, I'm not sure
that it should have been and would be interested to hear other's
views.

Hi, Cuz! Did you tell me off-list that your home sound card is broken?
Hmmm, how does John Starrett's applet work then, I wonder? But in any
case, if you _do_ have access to a working sound card or module, you can
produce MIDI music without a keyboard if you're willing to enter it by
hand into a text file, then translate the file into .mid using the
program I posted a couple of weeks back. Go to

http://www.egroups.com/files/tuning/

, change to the JdL directory, and download mhe.zip. Instructions are
contained in the file mheMan.txt, included with the .exe and a bunch of
.bat files.

One thing I forgot to include in that zip is a program that turns bends
(in cents) relative to 12-tET into actual MIDI bend messages, assuming
the default (and usual) bend range of +/- 2 semitones. If anyone would
like that, I'll post it. I am also, of course, available for any help I
might be able to provide.

Yes, please do get a MIDI keyboard, 61 or more notes, when possible
(with or without a self-contained sound module; older units like my Korg
M1 are not General MIDI compatible, so I use it more as a keyboard than
a synth now). Though you have little prior musical experience you will
have a whole new world available because of it. Heck, you may end up a
next great composer (perhaps after your new daughter is a little older
;-> ).
