Piano tuning by
no.1
software from app store

Or no.2 aural equal temprement tuning.

An intersting subject
With no clear answer which is better
Or preffered

I would dare says if you are very well taught with good aural temperment setting
Master,(teacher)
This method are the best.

But if a AETT self taught without proper coaching

Then probably fine tuning by software tuning might equal that.

But inorder to be
A qualified aural equal temprement tuner
One needs to be 1 taught n demostrate by a teacher n you will have to discard
Whichever software or scope
That helps you with the job.
And mind you
It takes me almost 10 years of
Practise to perfect the setting of equal tempremt setting by ear.

Modern technology
Have rendered it more difficult
To master the art of Equal temprement
Aural tuning.
So to enage a good tuner/technician
by ear
Is getting lesser nowadays

Fyi
Each note you either
X or divide by 1.0594631

And you will get the next frequency of
Each.
Semi tone

currently
I am only tuning
One piano per day.

apologise that i m not undertaking
Any tuning request here
Due to my backload n limited tuning each day.

Looking for a good refferral
