Hi Linda! I usually do short practice sessions because it difficult for me to find a big chunk of free time. I generally would start with a play through of the piece I choose to work on during the practice session, up to the point that I’ve learned. Then I do focus practice on spots that need work. I do take lessons with a teacher regularly, and he gives me a lot of practice strategies and tips depending on what is it that I am working on. Over time I learned to apply some of those practice strategies when I learn new music without getting a prompt from my teacher, which is very helpful when I want to work on something on my own. Many harp teachers offer one-off lessons to troubleshoot so that could be an option. Some people really benefit from being in a quiet place when practicing so they can have better focus. There are some pieces that I struggle with no matter how much time I put in; often times I will put these pieces aside and go back to them later. Hope that helps!
