How Do You Tune an Electric Piano?

04/05/2009 12:15 PM

My son rescued a Yamaha electric piano that got caught in the Great Iowa flood of 2008 at a theater in Cedar Rapids. The floodwaters came up to the very bottom of the cabinet and ruined the lower speakers, but none of the electonics were damaged. The insurance company totalled it out anyway because it looked awful, so he got it for free. It's a professional model, valued at $5,000 or so, and all it took was some cleaning and polishing and assorted pieces of the lower cabinet to make it look fantastic. He did not replace the big lower speakers, though, because they were very expensive. It plays through the undamaged speakers in the upper cabinet and sounds great to me.

My wife played it last night, and said it needed to be tuned, especially in the lower registers. So how do you tune an electric piano? We don't have a manual. Any chance the missing bass speakers affect the tune?

Hi Slow Old Poop,

good for your son!

it's best to not do the tuning yourself if:

  1. you're not a musician, that has an "ear" in determining if a note is right or not,
  2. you're not a technician who knows the inner workings of an electric piano.

electric pianos produce their tone with reeds, not with the strings of an acoustic piano. the reeds are the ones that need adjustment, so it is best to take it to a technician so work can be done properly on it.

your wife is right. the missing bass speakers emphasize the lower notes. the mid-range or high-range speakers can only partially produce them. an additional investment to replace the damaged speakers will surely still be a bargain for a $5K unit.

HTH!

GA Langyaw,

You really should replace the base speakers before attempting to tune it, however.

I picked up one in similar condition a few years ago. The new speakers did the trick.

I recently picked up an electronic tuner on eBay for about $10 - I can't believe they are so cheap now.

To answer your question, if you open the thing up you will probably find a bank of potentiometers (variable resistors) - one for each note on the keyboard. You tune it by turning the potentiometers. Typically, you will have to do it more than once, as the notes are somewhat dependent on each other.

If you can't find any such thing inside, then you have a digital keyboard that shouldn't need to be tuned - and the above suggestions about replacing the speakers might solve the problem.

--It sounds great .

well, I certainly believe you are not good at music. but your wife are, she can play and can heard accurate tune. as welll as your son.

langyaw is right. dont tune it if you are not familiar with it.

Obvioursly its a precious profession instrument. the price can match a string piano. Its digitalize. and ususally neednt adjust, unless the oscillator is something wrong. only a screw with a little turn, enough. because all tunes are produced by divider in IC.

I agree to them all. it might be base speaker or it amplifier. check them.

Mine's also changed a speak. but mines was not as expensive as yours.

You give almost no pertinent model information other than its a Yamaha Electric Piano, and obviously you have not searched on the web either as with one Google, I found many sites, not the least being the one noted below.

So pick your model and download the manual....if yours is not included, then you will have to search again.....GOOGLE!!!!!:-

It's not my piano, and it's not here. I was just asking if it is POSSIBLE to tune an electric piano, and the other more helpful respondents told me it is so. I will pass the HELPFUL information on to my son, and let him deal with it.

Google? What's that? Some kind of sandwich? Never heard of it. Sounds disgusting. I would never "google" something. I might do an Internet search, though.

...and you would most probably let Google do it for you. its the most "used" search engine today......

Also, it shows more thought for us here if you (in this case talk to your son first!) supply as much information as possible up front!!!

It stops the silly guessing games.....and the answers it generates!!!

Also, you could have done an internet search yourself with your limited infos and found out at least as much as I did!!!! You would actually have keyed LESS text than what you did!!

Hey -

thanks for that link!

I have a Clavinova, with a few keys needing some work, and hadn't yet thought about searching for a full manual to reference before digging in soon to service the works. Also, it's nice to get a full reference for considering what I might be able to...upgrade...while I'm at it.

Glad this came up today...;)

Sometimes - especially when you are looking for technical information - the good old Altavista gives better result then Google. The page ranking strategy of the Google can push back the site you would need just because those are not used frequently.

Are we talking about an electric piano, or an electronic piano?

somepeople think electric piano is one has only amplifier and speaker connected it.

but today. most people think no distinct.
