Invest in a dolly is one of the helpful tips for having a harp, especially if you are going to recitals, you're going to play at weddings, if you're just going to play for your church or an event. It's so awesome to have a dolly instead of having to ask your dad to carry your instrument all the time and have a car or transport system that can put their seats down. That is a helpful tip when transporting a harp.
My harp teacher did not let me see the sheet music for the songs that I was going to learn until I listened to the song five to ten times. So a helpful tip for just learning any music and music theory is to listen to the song and ear train yourself because then when you're playing the song you can realize whether or not you hit a wrong note. It's easier to pick up the notes especially if you're familiar with how the harp is laid out. So I would just listen to the songs that you're wanting to play over and over again and when you're not practicing I would like play it once in the car as I was driving like along with my Spotify playlist. So that's a helpful tip.
