There's no more cost-effective way to improving or changing your sound than a new head joint. Head joints are the heart and soul of any flute's sound. Head joints themselves are not all interchangeable. There are essentially four different "sizes" based on the diameter of the barrel of your flute. In many cases, your new head joint can be sized up or down a bit to ensure a proper fit, and a proper sizing is always included in your purchase. Moreover, there are essentially no "depreciable" parts in the head joint alone, meaning that there is no difference in durability between a previously owned head joint and a brand new one. Please check out our used and new head joint inventory. There is a new head joint right here at the Flute Center made just for you! One call and we will send out a few for you to find it!
