Types of Harps
The Celtic harp, folk harp, and non-pedal harp may all have different names but the overall design is the same. Each of them have between 20 and 40 strings (34 being the usual number) and are turned into a basic key such as C or E flat. These instruments are simpler and cheaper than the pedal and concert harps that have between 41 and 47 strings with seven pedals (allowing you to change the key of the instrument while it is played).
Decorative Harps
Many antique collectors covet decorative harps and their prices may be steep. For example, a Naderman style Hook Harp is sold by one retailer for nearly $4,000. A black and gold Dodd 43-string harp that has undergone physical but not musical restoration sells for over $7,000. Often times, harps may be purchased at auction. For example, John Moran Auctioneers has a 1915 Harp from Lyon &Healy (one of the oldest and largest harp manufacturers in the U.S.) that is estimated to get bids between $4,000 to $6,000. Another factor that can enhance the value of an antique harp, decorative or functional, is whether it still has its original case, tuning tools and any other accessories.
Restored Playable Harps
Restored playable harps are extremely valuable. For example, H. Bryan &Co. currently sells a Lyon &Healy, Style 22 Harp for $23,575. They also sell a Lyon &Healy, Style 17 for the slightly less astronomical sum of $23,212. An 1866 Erard Gothic that has been re-gilded in gold leaf goes for $27,875. Many restored harps come with a five-year guarantee. Given the value of these instruments, consider asking for one from the vendor if it is not already included.
Harp Restorers
Harpmall.com offers an excellent guide to the small world of harp restorers. They may perform simple maintenance over playability adjustments as well as painstaking detail work to bring antique harps to their former glory. Often, the most visible flaws such as a large crack in the base are not nearly as difficult or expensive to fix than more subtle aspects that affect its sound. The cost of restoration varies according to individual cases but be prepared to pay a premium as there are few experts in the field of harp restoration.
Reproductions
If you simply would like to play a harp, consider purchasing a reproduction of a classic model. Truth be told, a pedal harp still may sell in the low five-figures but a new instrument may have less potential problems than an older one. In particular, Clive Morley Harps in the United Kingdom sells an excellent variety of new and used harps.
