If you don’t know what wires you need, you can look at my stringcharts page, or get in touch and I will be happy to advise.

I can cut whatever length you want. The price is £2.50 per meter (2½p per cm).

Yellow brass wire

I recommend Malcolm Rose’s yellow brass wire for stringing your harp. I have the following sizes in stock (nominal diameter in mm):


Soft iron wire

If your treble strings are too long for brass, I recommend Malcolm Rose’s soft iron wire. In theory you can string the entire harp with iron wire; I asked Malcolm to make the thicker sizes as a special order for me, but I have not yet got round to trying an all-iron setup. Maybe that will be a project for the coming winter. I have the following sizes in stock (nominal diameter in mm):


Red brass wire

Some people like to use red brass in the bass of their harp. I have tried these on my harps but I don’t use red brass basses any more. In my opinion red brass has a duller sound and doesn’t speak as well as yellow brass. I have the following sizes of 90/10 red brass from Malcolm Rose in stock (nominal diameter in mm):


I have the following sizes of 85/15 red brass from Rio Grande in stock (nominal diameter in mm):


I have the following sizes of 85/15 red brass from Marc Vogel in stock (nominal diameter in mm):


The strings are attached inside the harp with hardwood toggles. These are 30p each on their own, or £1.80 each wound onto the ends of your strings (though I don’t recommend having individually toggled strings – it is much better to wind the toggle onto the wire inside the harp before cutting the string to length).

You can download a free instruction diagram showing how to wind the toggles and how to install the string on your harp. Or you can come to Armagh (bring your harp if you want!) and I can show you how to do it.

Always use hardwood dowel – the wire can slice through softwood.

Yellow brass is also sometimes known as cartridge brass or spring brass. It is made from 70% copper and 30% zinc. You can use any 70/30 brass wire for making harp strings.

The reason I prefer Malcolm Rose’s wire is because he makes it especially as old-style music wire, controlling the hardness and crystal structure of the metal for the best sound.

Here are two short videos, where you can listen to Malcolm Rose talk about his work making the wire:

Malcolm Rose died at the end of 2022. I understand that his daughter Leonie will continue the business. In the meantime, I still have lots of reels in stock here.

Strings for Other instruments

While my main business is the full-size traditional wire-strung Irish harps, I am happy to also advise or supply strings for other wire-strung instruments, such as medieval harps, psalteries, harpsichords, etc. I can wind a harpsichord-style loop on the end of a string if you want.
