The technique of playing both the Celtic or “lever” harp and Concert or “pedal” harp (also sometimes called Classical harp) is quite similar but they have a lot of differences in terms of size, price and repertoire. Concert harps are vastly more complex than lever harps and so come with a higher price tag. Lever harps usually have between 22 and 36 strings and are generally smaller in size while Concert harps usually have 44-48 strings and often have an extended soundboard at the bass end for added volume. Wedding Harp Players normally use Concert Harp.
