Psalm 144:9 KJV says: " I will sing a new song unto thee, O God: upon a psaltery and an instrument of ten strings will I sing praises unto thee." I had the psaltery and now I have the instrument of 10 strings too. How cool is that! I bought mine on ebay - finding it under the "psaltery" search. I found it was tuned similarly to my 11 string psaltery. The strings are normally tuned ABCDEFGABC - low to high starting on the left. I tuned mine to the key of D by changing the 2 Cs and the F to C# and F#. The strings don't have the nice ring the psaltery has - ukele type strings I think. Still a very interesting instrument and I'm having fun with it. I don't have to re learn songs thankfully - just getting used to plucking notes instead of bowing them. This instrument dates back to Bible times, was thought to have been played at the battle of Jericho and is depicted on coins of that period. The first song I learned to play on this? - "Joshua Fought the Battle of Jericho" - only seemed fitting. You can find out more about these at www.battleharp.com . Strings can take about a week to settle in, so no videos until the strings stabilize a bit. The body of this instrument is oak. Front and back are made of cedar.
