Hi Judeth- Lots of us newbies have to come to our harps after life changing events, and found that the harp itself can be the most life changing of all.
If your harp is tuned in Eb, you need to raise 2 levers before the red C strings and one before the blue/black F strings. Try that, play a scale, and see if it sounds right. If not, let us know. Your teacher will not embarrass you- I have a degree in music education and it took me a long time to figure the levers out, and I’m not always sure even now. Keep us posted!
