I try to approach even warming up and technical work with as much musicality as possible. It can be difficult to “feel it” when we’re playing lip slurs, in particular. But since the voice was our first instrument, songs are helpful at moving us away from managing the trumpet to making music through it. I realized that much of the first phrase of the well-known hymn, Amazing Grace, is a lip slur. So, I thought it would be a great way to approach what is a daunting task for many trumpet players.
Play these through with all fingerings, noting where valve changes are required. I included the first line text to remind us of how it goes. For even better results, sing each phrase through before playing.
