Types of HarmonicaEdit
Harmonica Construction and ComponentsEdit
Although harmonicas do not lose their tuning over a sessision as stringed instruments do, older harmonicas and harps of lower quality may be a bit off key. If this is the case then one may purchase a harmonia tuning kit with instructioins on its proper use.
An alternative for the more experienced harper is to create a new harp. Using the aformentioned kit and a layout of the desired harp one could replace keys to create the desired effect. It is suggested that this be attempted on a old harp that you no longer use.
