For me, easier done than said. When I am done I will check the 3rd's and 6th's by themselves and with the G7, Eb7, A7, and Bb7. I can hear the 6th's and any 5th's that are too wide. I will do other checks as I go if needed. As long as I get it right I will not have to go back and redo. Although sometimes i will get up or down the scale and find something not quite right and have to backtrack, but not anything too bad I can't correct easily.


I see, now (perhaps) I get it better. But then I get lost:

..."So it will be tuning D from A, (3rolls sharp)...

I understand D4 from A3;

..."G from D, (2 rolls sharp)...

G3-D4

..."C from G, (3 rolls sharp)...

C4 from G3

..."F from C, (2 rolls sharp) then octave F, (above),...

You mean F3 from C4? Then F4?

..."Bb from both F's, (F3 2 rolls flat, f4 3 rolls sharp)...

Here (perhaps) I get lost. Is it Bb3? And the 4ths F3-Bb3 rolls less than the 5th Bb3-F4?

The temperament is between F3 and F4. All 5th's I do are 3 to the sharp, and all 4th's are 2 to the sharp. If I do A to E it will be 2 to the flat. Instead I tune the E from the B because it will be from the top and be 3 rolls sharp. If I get it right the A from E will be 2 rolls flat. I always tune from the sharp. It is easier to come form the top to set the pin than from the bottom.

The false beat appears only when there is felt mute.

About your latest fifths: there is one fifth that is very noticeably beating, C#-G#. Compare that with C-G and let me know if you can hear a big difference.

Perhaps it is time to consider one important fact: when a fifth is very very close to just, you must make sure (be sure) that it is on the correct side, namely narrow. In fact, our ear would accept almost-just fifths that are almost-just/wide, but - for example, in general - we want D4-A4 almost-just/narrow.

Let's consider the base intervals, make sure that A3-A4 is just-wide… how do you know (for sure) that A3-E4 is narrow? You have two ways: gently force your hammer (E4) ccw (counterclockwise) and see if the beat gets faster, then it was narrow. Alternatively, make sure that E4-A4 is wide.

When ever, perhaps you want to exercise your musical ear: fix one note (only centre string), go up to its fifth, tune left string (beating) narrow, right string wide, play slowly, mute in turn right-centre strings // left-centre string and try to relate the narrow and wide beating with abstract "tension" and "mood".

A narrow fifth is flabby and sad, loose and mournful. When ever please, you tell me how you "feel" a wide fifth.

Back to your latest fifths and 3rds. Ok means almost Ok.

1 - A3-E4: Ok, perhaps wide?? In fact C4-E4 is very tense, too wide;
2 - A#3-F4: Ok, in fact C#-F is Ok… BUT…
3 - B3-F#4: Ok, in fact D-F# is Ok;
4 - C4-G4: Ok, in fact D#-G is Ok;
5 - C#4-G#4: far too narrow, in fact E-G# is too sweet;
6 - D4-A4: it moves too much, I would have checked A4, perhaps it went a bit down.

Consider 5, you want C#4 down (in pitch), consequently F also down.
You tuned C#-F# too just and D#-G# too wide. This makes B3-D#4 just (pure).

Beat-wise, try to place C#-F# in between A3-D4 and E4-A4. In general, tune and compare every new interval, go correcting the most evident over-beating. Can you spot/confirm point 5?

Buona Domenica, a.c.

hello Rich I imagine the tuning as much appreciated for popular music, I suppose. I really wish I could hear a sample . If you think about it you are also respecting some model( I am unsure the word equation apply there)
I still dont understand your test with notes in the 7 octave. Or do you mean 7th?
best regards.

that is fun how we can get used to an interval quality. for instance enlarging tend to favor the projection of tone, I have seen a tuning done with small octaves that was pleasing singers but could not be used in concert without miking.

Thank you. Noticed the C#-G# beating.

Point 5, not sure if I understand.
If C#4 too low in pitch, that's C#4-F#4 too wide.
C#4-G#4 too narrow, then D#4 will be too low, then A#3 and F4 also too low. Is his the meaning of point 5?

Practice again tomorrow.
Will tune C4-G4 center string to pure fifth, then G4 left string lower a beat, right string raise a beat to listen the different of wider/narrower tone.

Thank you.

Thank you, Weiyan.

You noticed C#-G# beating, very good. It is beating because it is a very narrow 5th.

You can look at that in two ways:

- G# is too low from just (in pitch); in this case you raise G# closer to almost-just 5th;
- C# is too high from just (in pitch); in this case you lower C# (closer to almost-just 5th);

I noticed the 4th C#-F# non-beating (it is too just): in this case if you lower C# you can adjust (at least) two intervals: C#-G# gets (correct) wide and C#-F# gets less narrow (less beating - closer to just).

Please notice the chain of effect (events?): look at point 2 (A#3-F4), C#-F (as a M3) is Ok; if you lower C# you have to (must) lower also F.

In general, that is what you need to develop in time, the ability to visualize the chain of effects for every move.

In general, evaluate the effect of each move and try to improve (at least) two intervals with one move.

Always ask yourself: what happens (to the other intervals) if I modify this interval? You can do also this exercise (*) in abstract, even reasoning with yourself, without moving anything.

Regards, a.c.

(*) Edit: so doing, you will be able to draw the "intervals relation map".

Thank you, Afredo.

I always doing mental exercise.

Had tuned for hours, still cannot reconcile C-G/D-G. G4 is last note to tune, the problem is inherited from C#4.

I don't expect any result in first few tunings, just for building up the sense of geometry.

Good comment, Weiyan.

In a while, when you are ready, I'll tell you more about the sequence. Make sure that intervals are on the correct side and... Do not forget to take a brake, things go deep down...in time.

Godd morning.

To get last minute advice before today's tuning session.

Thank you for reminding taking brake. Try to slice to 30 minutes sessions.

Analysis of sides of fifth:

A3-E4,
Tune center of E4 to pure fifth. Higher partials seems beating. There is beating at attack. The fifth may not pure.
Tune left to beat at lower side,
Tune right to beat at higher side.

Its hard to distinguish the side of fifth.

Corrections:

Lower D4, and fine tune the fourth progression.

D4-A4 seems beat too fast. The A3-A4 may too narrow. Should raise A4 little.

http://soundcloud.com/weiyan-1/thirds-c-11-june-2012
D4-F#4 slower than previous interval

http://soundcloud.com/weiyan-1/fourths-c-11-june-2012

Hi Weiyan,

I have heard your rec. (previous post).

I am really happy for what you are able to hear. Also your written move (previous post) was correct.

I will be more precise later on. Well done.

Alfredo is faster to help you with structure, I appreciate it it give me a rest wink Thank you Alfredo.

It is easy to be confused between too large 5ths(beating slow) and too small (correctly beating).

I usually recognize that immediately on a piano because of the behavior of the activity, too straight and at the same time unbalanced, but on the recordings I can get confused easily, I find.

Weyian you are progressing at the speed of light (of sound I may say wink . Let me suggest to you both that when recording the 5ths or the 4ths you sequence them in the same order than the temperament. That would make it easier for all of us to find the relations.
What do you think Alfredo ? chromatic sequence may be used later.

Also, the M6th are very useful . May be you could record 6 notes in sequence from the beginning of the temperament, then 7 , etc.

I understand well you are working on 4ths, 5ths and octaves (the octaves begin to be quite good and you are hearing and thinking "structurally" which is what is necessary.

Once the basic reasoning is obtained, you can tune directly the sequence, as mistakes are more easily corrected when more notes/intervals arrive , for instance the A3 F# sixth give yet a first idea of whenever the precedent intervals are good or not.

Congratulations on your tuning lever precision BTW That is amazing to follow your advancement.

Yes, Isaac, once again you have read into my thoughts! You see, perhaps we both are from a different planet ;-) but yours is still... faster!

I did think of asking Weiyan for the sequence exact order recording, then I read "G4 is the last note" he tunes... that is why I wrote ..."In a while, when you are ready, I'll tell you more about the sequence."

How nice to see that you too are "there".

About 6ths, it is precisely as you say, A3-F#4 gives the first FBI measure and relates this FBI with the previous SBI's; we evaluate that 6th out of its tension, taste, flavor, I'd say intonation... I'm sure we'll get there too.

I open all Weiyan's recs (M3's, 5ths and 4ths) and play the intervals jumping from one window to another one, so I can follow many relations at once, like if I was to play.

I'll be back soon,

A l f r e d o

Isaac sent me the tuning procedure.

A4->A3
A3->D4
A3->E4
E4->B3
B3->F#4
F#4->C#4
C#4->G#4
G#4->D#4
D#4->A#3
A#3->F4
F4->C4
C4->G4

It usually leave the gap in C4-G4/D4-G4

In the procedure sheet, after tuning F#4, check with sixth. I think its A3-F#4. Should you tell me how to use this checking?

Thank you.

Weiyan, please do not feel sorry, I am very happy when I can be of help, and your desires and efforts may help others too. So… we may all be happy.

Thirds:

A3-C#4: about 5 bps - too sweet, should beat faster, more tense;
A#3-D4: nice/a bit too fast - you can hear it is sensibly faster than previous;
B3-D#4: nice - very similar (slower) to previous - that difference is advanced stuff;

C4-E4: almost Ok - slower than previous;
C#4-F4: almost Ok - you hear it is sensibly faster than previous;
D4-F#4: too slow - compare with A3-C#, you hear it is similar - you want it similar to previous;
D#4-G4: not too bad;

E4-G#4: leave these out.
F4-A4: ==

Let's consider 5ths (it is a very important "harmonic" interval and you said A3-E4 is difficult, let's work on difficulties first):

1 - A3-E4: you can hear some movement… but… C4-E4 is quite nice, very little slow;
2 - A#3-F4: nice - but C#-F4 is a bit tense (too wide) - compare C-E and C#-F4, C-E about 8 bps, C#-F4 is beating as a flow, not countable;
3 - B3-F#4: too much movement, check D4-F#4, slower (sweeter) than C#-F4…
4 - C4-G4: nice - check D#4-G4, nice:
5 - C#4-G#4: too much movement, check E-G#, nice
6 - D4-A4: it moves too much.

- . - . - . -

After your corrections.

Your analysis was correct! You have improved C4-E4 and D4-G#4; at this stage, refine the M3's similarities: A3-C#4 is too slow; C#4-F4 (too fast)//D4-F#4 (slow) these are too different.

Perhaps A3 can go down (in pitch), so A3-E4 gets closer to narrow-just and A3-C#4 gets faster;
Perhaps D4 down, so A3-C#4 and A3#-D4 get more similar and D4-F#4 gets wider (faster);
Perhaps A#3 up, so A#3-F4 gets narrow and A#3-D4 more similar to neighbors;
Perhaps C4 down, so improving C-E and C-G.

As Isaac said, you have done a great job. Now, also move on above A4… use octaves (almost-just // on the wide side) and 5ths (almost-just \\ on the narrow side). From F4-C5 up… go for octaves (almost-just // on the wide side) and aurally beat-less 5ths.

I see you have posted, I'll reply later.

Regards, a.c.

Thank you.

Excitintg! Two weeks before, I even don't know how to hear beat. I couldn't believe I could move a pure fifth narrow little to beat 0.5bps. Issac can give witness.

Try climb up to A6 to day.

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.

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.

C4-F3 Slow

A#3-F4 Slow
A#4-G#4 Fast

Had correction after recording. Sorry for no record.
The wrong beating mostly due to pin setting problem.
http://soundcloud.com/weiyan-1/octaves-f3-g-4-13-june-2012
Octaves F3-C#4

http://soundcloud.com/weiyan-1/octaves-d4-g-4-13-june-2012
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.
