Wire

I recommend Malcolm Rose’s yellow brass wire for stringing your harp. I have most gauges here in stock. I can cut whatever length you want, at £2.50 per meter.

If your treble strings are too long for brass, I recommend Malcolm Rose’s soft iron wire. I have some gauges in stock and I can cut whatever length you need at £2.50 per meter. I have these iron treble strings on my copy of the NMI Carolan harp and it sounds great. See my stringcharts page for more information.

Some people like to use red brass in the bass of their harp. I have some stock of 90/10 red brass from Malcolm Rose, and 85/15 red brass from Marc Vogel and from Rio Grande. The Vogel red brass is £5 per meter; the others are £2.50 per meter. I have tried all these on my harps but I don’t use red brass basses any more.

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. You can download a free instruction diagram showing how to wind the toggles and how to install the string on your harp. Always use hardwood toggles – the wire can slice through softwood toggles.

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


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:


Strings for Other instruments

While my main business is the big floor-standing 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.

String marker pens

I don’t use or recommend coloured strings; if you use the traditional old Irish harp playing techniques (as described in Sylvia Crawford’s book) then colours are completely unnecessary. However some people still use the classical harp system of red and blue coloured strings, and so I do still have limited stock of acrylic marker pens which can be used to add colour to metal wire strings. The colour can be completely removed by rubbing with a damp pot-scourer. £7 per pair (one red, one blue).
