Hi Weiyan,

It is good that you go up the scale, give your ears (and pins in the middle octave) some rest.

Perhaps you have a brake and can read this.

A3 and C#5 give you a 10th. You go up the scale and you can listen to the chromatic 10ths progression (ccompare beats), so that you can refine your aural skill for FBI's.

Evaluate beats, and also try to distinguish other intervals issues, like tension (low/high) or taste-flavor (sweet/acid).

Have a nice day, a.c.

Sorry haven't tuned today.

I have a criminal slander case.

The police opened a file of a man use an private Email as witness to accuse me slander. It's strange here slander is criminal case, use private email as witness is super terrible. For example, I send email to Issac back mouth Someone. Then Issac forward to Someone. Someone use the email to accuse me. Police may charge me with this email. Nearly no freedom here. I go to relate party to complain and have appoint with a regional Councillor tomorrow noon.

So sad.

Sorry for out topic.

Hello weyian I am sorry to read that. i am unsure I get it all. The privacy seem to be a different concept than I thought but seem to me that there is attack to ors by forwarding a private mail.
I hope. it will turn to a good end.

All the best.c
Isaac

Issac,

Thank you. Sorry for don't further reply any matter about my legal case. I don't want to spam this thread. I post my case here to let others know I still working at CHAS.

Hi Weiyan,

I too am very sorry to hear that. Stay calm, things will hopefully get fixed.

Missing your birds... Keep in touch,

Alfredo

I would like to reach you, Weiyan, with my best wishes for tomorrow's meeting.

Good morning.

Haven't heard Chinese music for tens years. Liu Fang had expressed a Chinese heart with Pipa.



This a saying of Confucius about music, hand written by me with round brush.

Start today's journey.

Hi friends,

This is today's freshly baked crack potter.

Sorry for its raining today, so no much birds whistle.

Octaves D4-G#4

Alfredo asked me to tune the octaves up. Sorry, I tune up and down, not followed the instruction strictly. Its strange tune the octave before the temperament is OK. Its magic that when tuning the octave, the errors in temperament are enlarged and easily be fixed.

Weiyan's naive tips today:

Move before the potter is crack. Then crack it from outside.

Just tune the octaves down to C1.

Its interesting to tune by fifth.

For example:
Tune A3->A2
Tune C3->A2 from narrow side, until there is marginal beat. The octave is ready.

After tuning the octaves, test by 10ths, they are nice and consistence. Test by chords, the voice is open.

OMG, some chords are sour. Actually some thirds out of control. Still take some more time to practice. The pin setting is next target.

Why its easy to crack? I found that a very slight crack in A3-A4 octave, the crack is enlarged in octaves. Fortunately, its easy to amend. Its easy to locate the crack.

Aflredo didn't tell me the procedure explicitly. Yesterday instruct me to tune the octaves, tune the fifth marginal narrow. After hours practice octaves, I get what you said. You seems a great teacher who never give explicit instruction, just let the student to discover it. How amazing.

I had asked Issac why call it pre-tuning instead temperament. Issac didn't give me an answer. Its better to let me discover the answer. After days of practice, I try to sum up my impression of CHAS.

For CHAS doesn't have temperament concept as ET do. In ET tuning, tune and fine tune temperament octave, then extend to octaves. Use this concept in CHAS is disaster.

In CHAS, all 88 notes is a temperament. Pre-tune A3-A4. When the progressions near OK, tune octaves. If fifth and octave cannot reconcile, there is a crack. Amend the crack.

Good night.

Hi Weiyan,

It will be evening in Honk Kong when I will be able to reply. Your hand-written saying is very nice, could you translate that saying by Confucius?

Now at yours it is almost... Good morning, a.c.
.

Good morning.



This may be the most abused, most misinterpreted Confucius saying. Music is the second of Confucius' six subjects in education.

Hello Weyan, I like your comments there..

Sorry about the pre-tuning, it is a mean to anticipate the instrument settling, it uses the way the piano is reacting to more tension, that is why intervals are enlarged more than what is expected in the end.

When using that process , at each tuning you developp a feel for the settling of the piano, something that is computed by the ETD in PR mode and then be done by ear (you gain a better knowledge of the process, which differs in the bass and the high treble, hence the strip muting of only the mediums and the beginning of the treble.

It oblige the tuner to learn something new in terms of pitch appreciation but provide a way to work in one (longer) pass.

Thank you for your writings, that is refreshing.

I will listen later to your records but the little bit I heard let me say : "that is yet better than the last time..."

I recorded me unreasoning and correcting a vertical while going from 445 to 442 Hz (I forget to record since I finished the "pre tuning" ) I should edit the file as it is long (1 hour) because I work on tone quality , that slow the process.

Best wishes

Hi Issac,

Sorry for the link is broken.

Better to ignore previous records. Tomorrows far better than yesterday's.

Today tune the whole piano. The voice is very open, may be too open. Tomorrow tune again and post some record.

The procedure I used to tune octave:

A4-A5:
Tune A5 from D5 to marginal beat at narrow side. Then check A4-A5 if it beats.

A3-A2:
Tune A2 to E3 to marginal beat at narrow side. Then check A3-A2.
Bass tune very nice. Parallel 8th is very open.

Also check with 10th.

Not sure if this method OK.

EDIT:

This record can give an impression of the tuning.

BYE.

Hi Weiyan,

Thank you for translating Confucius' saying, his depth is sound and silent. You have also added two words to my vocabulary: "jargon" and "amend". uoy knahT.

Let's see your fourths, where you did Self C.: "A#3-D#4, D#4-G#4 FAST, C4-F3(?4?) Slow"

A3-D4: about 2 bps, too wide
A#3-D#4: about 3.5 bps, too much, B3-D# is a bit sour, you were correct
B3-E4: almost Ok
C4-F4: almost just (beat-less), you were correct
C#4-F#4: about 8 bps, too much
D4-G4: about 2.5 bps, too much
D#4-G#4: about double the above, too much, you were correct
E4-A4: nice, a bit slow

Your base:

A3-A4: good, a bit shy, make it wider, you can always get it down (with a forte blow?)
A3-D4: perhaps wrong side?
D4-A4: too moving, wrong side?
A3-E4: nice!
E4-A4: shy, weak, make it more nervous;

Thirds:

A3-C#4: better than last time, still a bit slow
A#3-D4: slow, loose, sweet, slower than previous
B3-D#4: fast, very tense, check A#3-D#4 (too wide), perhaps D#4 must go down?

C4-E4: about 3.5 bps, even slower than A#3-D#4, too slow
C#4-F4: very tense, too much, beats are in a flow
D4-F#4: nice, tense-harmonious and singing
D#4-G4: sour, check D4-G4 (too wide)

E4-G#4: a bit slow-nice
F4-A4: nice, check C4-F4, raise both pitches
F#4-A#4: I usually tune A#4 comparing the previous 4th, 5th and octave
G4-B4: too sweet - here 3rds are savoury, a bit salty

Project:

G4 down (in pitch)

A#3, C#4, D4, F#4, A4 up, raise their pitch

Check 5ths:

1 - A3-E4: nice
2 - A#3-F4: nice, if you raise A#3 (see project), you raise also F, so you can correct C4-F4
3 - B3-F#4: too still, B3 up so B3-D#4 gets less wide
4 - C4-G4: too still, too just, leave a slow/late opening, G4 down (see project)
5 - C#4-G#4: too early movement, about 1 bps, perhaps wrong side?
6 - D4-A4: make it more still, less activity, A4 and D4 up (see project)

You have written very nice things, I'll be back later, I enjoyed birds singing.

Alf.

HEllo Weyian :

Yes the tuning was so long it could not be uploaded or treated, I dont know.

Here is a part of it :http://soundcloud.com/olek-4/unisons-corrections

http://soundcloud.com/olek-4/unisons-corrections

Sorry I will write later...

Hi Afredo,

Thank you.

The A3-D4 at wrong side. I found out it later.

"amend" is to modify for the better. This may be wrong wording.

"jargon" is bottle neck.

Hi Issac,

Thank you for the sound file.

Hi Weiyan, I listened to the recs below:

..."Had correction after recording. Sorry for no record.

- . - . - . -

Perhaps you yourself can notice that some intervals need to be corrected. Let me know.

..."Alfredo asked me to tune the octaves up. Sorry, I tune up and down, not followed the instruction strictly."...

No problem. Do you have the Flow-chart (pdf.) of the sequence already?

..."Its strange tune the octave before the temperament is OK. Its magic that when tuning the octave, the errors in temperament are enlarged and easily be fixed."...

Yes, enlarging the mid-range, all intervals reflect - step after step - their individual chromatic tensions, showing their long-distance coherence.

..."Weiyan's naive tips today:

Move before the potter is crack. Then crack it from outside."

Thank you.

Alf.

Good afternoon.

These are today's practice session.

C#4-F4 seems too slow

http://soundcloud.com/weiyan-1/fourths-15-june-2012
A#3-D#4, D4-G4 too fast
E4-A4 seems very fast in the record, but listen to the piano, it seems OK.

http://soundcloud.com/weiyan-1/fifths-15-june-2012
G#4 too flat, had been raised after recording.

Use only 1.5 hours to tune these 12 notes. Among 1.5 hours, slept one hour.

These is today's corrections.

Please ignore previous recordings. This is the final submission of today.

After days frustration, things become easy.

In 8 o'clock evening, complete tuning all octaves and unisons.
Below is a test playing.

Thank you.

Hi Weiyan, good evening.

From the base:

A3-A4: OK- too still, up a little bit
A3-D4: too wide
D4-A4: too much noise, up A4 and down (forte blow?) D4
A3-E4: too narrow
E4-A4: a bit wide, up E4 (and A4)

Fifths:

A3-E4: it moves too soon, it is a bit too narrow, check C4-E4… it is Ok, remember this;
A#3-F4: too narrow, about 2.5 bps, check C#4-F4, too slow, too sweet, 6 or 7 bps, more typical for F3-A3//F#3-A#3 (that area)

B3-F#4: nice, check D4-F#4… nice
C4-G4: too narrow, about 1.5 bps, check D#4-G4… nice, remember;
C#4-G#4: like above, check E4-G#4… Ok… try to remember (*)
D4-A4: make it closer to just (see the base)

Project:

Up E4, check C4-E4…, up C4, check (4th)… up F4… solve A#3-F, up G4 (remember D#4-G4?)

Forths:

A3-D4: too fast, down D4, check A#3-D4, too slow… down A#3, in direction of A#3-F4 (maybe ok? see project)
A#3-D#4: wrong side? check B3-D#4… nice! check D#4-G#4… fast, up D#4 (join G4, remember?)... down C#4 (*)(remember?), solve A3-C#4 (a little bit too sour (fast)) and C#4-G4 and C#4-F4.

The deeper we go, the thiner the adjustments will get. Control your body, relax your ears, breathe natural (calm). Enlarge your temperament, yes, and follow chromatic intervals coherence.

Please, let me know about two questions (in my previous post).

I'll be travelling until Tuesday, have a nice weekend.
