    Hi Juan! My piano is some 20 y.o. and I’ve had two tuners work on it previously. Both of them told me that the piano is a half step lower than it should be, but this is how it was built and they cannot do anything about it. Is there anything to be done about it, just that it would take a lot more time to tune it properly? Maybe if I would assure the tuner that he will be paid by the hour, just so that he gets the job done, he would be willing to do it … Thank you!

    Hi Juan,
    I wish to get more information about muy piano KAPS P. VAN LEEUWEN & Zn Amsterdam and this 2 Numbers 6330 and 263 and price.
    Many thanks!

      Hi Toñi,
      Sorry, I do not have any reference about your piano. I think it could be what they call a “stencil piano”, that is a piano built by large factory and labeled with a manufacturer’s name not related to the factory. Very often they use the name of a well known piano or music store.

    I recently bought a home with a beautiful piano just abandoned there, so unloved. It is a Hardman &Peck baby grand with serial number 110010. It was very loved at one point because the condition is superb. However, I believe it is out of tune. Do you have any information on this piano? Unfortunately, the house was bought as a rental so I need to find out if it is worth moving to my primary home or if I should sell it and put the money into a new piano fund. Thanks so much in advance.

      Hi Katheleen,
      Your piano was made in 1956 in New York. If the piano is well looked after and is in a good condition it looks like a nice present, I wish I had your good luck! If it is out of tune, contact a technician to tune it, but if it has been too long without tuning it might need a secondary tuning and some regulation. Best thing is to call a pro piano tuner to give you an estimate.

    I have a question about my upright piano. its quite old, i took it apart as by that i mean i took the Hammer rail system completely out and when i put it back in, suddenly some of the hammers seem to be stuck against the strings without the key even being pressed, this makes it impossible to press down the key and is annoying the crap out of me and i would really like to know how to fix it myself, somebody please help.

    • Juan says:

      Hi Paul,
      I guess what you mean is that you removed the action from the piano and could not place it back properly in place. It looks like you did not set the action properly into their bolts. Try again to remove it and then carefully put it back. If it does not work you can send us some pictures and will try to help you. Regards, Juan

    I have a Kaps 6 foot grand piano serial number 7265. The patent is from 1878 Dresden. It has been repaired but not particularly well. Sound board and pin board are fine. It holds tune better and better with each tuning (3 so far in the past year). Can you tell me what year this piano was made and what the general opinion is of this make and model? I have a professional in to tune once a year but it does have some issues in between and I would like to start tuning it in between the professional tunings (do you think this is wise?). Thanks for you advice and opinions.


    • Juan says:

      Hi Ravil,
      No wonder you have some issues in between tunings, your Ernst Kaps piano was build in 1882!! It is not a well known piano, production was discontinued by 1930, so you do not see many of those Kaps around. Yes it is wise to tune the piano yourself in between pro tunings, that is what many people already does. You do not have to be a proficient tuner to better your piano, and it is amazing what a few “little touches” like adjusting unisons and octaves (within the reach of practically everybody) can do for your piano. These techniques surely you can learn, we’ll be happy to help.

      Best wishes for the new year,

    Hi Juan,

    Thanks for all the great information. I have a question. I have a brand new (4 years old) Yamaha Grand and I am going to attempt to tune. I have tuned before a few notes on several pianos and being a musician for all my life, I know and can tell the beats and interval and unison tuning you talk about.

    My question id when I just checked the A above middle C, it is flat -20 cents on my Korg OT-120. It seems like all the notes are flat -20 cents. Do you recommend I bring the temperament up 20 cents to be dead center in tune? Is this to much of a raise in pitch to cause problems and break a string(s)?

    I greatly appreciate your reply.


    • Juan says:

      Hi Ray,
      20 cents down in pitch is not too flat, in fact it is quite ordinary. 20 cents is the equivalent to 5 beats (4 cents = 1 beat), that means your piano it is roughly at 435 bps.

      Yamaha grands are in general pianos easy to tuned, beats are easy to hear and recognize. To do a good job I recommend you tune the piano in two times. First time bring the piano to standard pitch 440 bps (at this stage do not need to be too precise) and let the piano settle down for one or two days, then fine tune again, this second time try to be as precise as possible with special attention to the unisons. I think by following this procedure, your piano will nicely tuned. Remember to strike the keys solidly (very important) in order to settle down the pins. Good luck!


      • Ray says:

        Thank you Juan.

        I will give that approach a try and tune two times. I appreciate the great information you provide on your blog.
