A pitch raise requires more time and effort than a regular tuning. If your piano has not been tuned in years, it is more than likely so flat that the chances of fine tuning it in one pass will not hold the strings to their proper tension and pitch levels. The purpose of a pitch raise is to bring up the piano strings' tension levels before proceding with a fine tuning. It is highly recommended that your piano be tuned at least twice a year to prevent further damage in order to keep your cherished piano healthy.
Repairs
What's that annoying sound? It could be a loose hammer, a loose screw, a broken string, or the key itself. Are you splintering your thumb or index finger when you slide down the keys like Jerry Lee Lewis? I also repair keytops.
Regulation
Each key has many points of adjustments which need to work together to produce the sound you hear when you play just one note. For example, sometimes the pianist may experience too much or too little key dip. Maybe there are a few keys on your piano that feel a bit sluggish in repetition because of a friction problem. Regulation is best described as 'adjustment of action parts.' Action parts should be consistently regulated to achieve the full energy being transferred into the key. Remember that all your energy starts at the keytop.
Happy Songs
After your piano has been promptly and carefully serviced, I will play a very short musical piece at random. This is for you to hear what your new fine tuned piano sounds like. There is no extra charge for this part of the service. :)
