Tuning of Musicical Instruments

This chromatic strobo tuner is originally designed for the tuning of musical instruments such
as Pianos, Organs, Accordions, Harmonicas or wind instruments and etc. in their factories.

Tuning of Piano

Usually piano should be tuned in accordance with the curve of "Stretch" shown in the operation
manual of this tuner. As shown in the "Stretch" curve for the tuning of piano, higher and lower
frequency will be stretched slightly. Each scale has in general fixed amount of stretching and this
amount also changes in few cent depending upon the individual taste of the pianist or experience
of the tuner.

Tuning of the reeds of Organ, Harmonica and Accordion

Usually set red indicator to the zero point of the dial.
Then blow the reed to be tuned in front of the microphone. If it's the sound of "A" the pattern
will appear in the "A" window. If the pattern rotates slowly to the left, the sound is slightly lower
than the standard. In this case, shave the top of the reed slightly with a file.Then blow the reed
again, if the pattern comes to a standstill, it's perfectly tuned. All that is necessary, is to shave
the reed so as to produce a statonary pattern.
