Playing a pentatonic melody on a Native American style flute is actually a bit harder, especially for a beginner. With a NAF you have to think about breathing, squeaking, tuning, and the finger holes are impossible to see.
Have you ever seen a person being shown the black keys on a piano and then told to, "Play from the Heart"? Of course not. That would seem like nonsense. You would expect someone trained that way to play a bunch of disconnected, random sounds. Yet that is exactly the only training most people get on the NAF!
While it is true that anyone can make sounds on a Native American Style Flute, the NAF is still a musical instrument and making music with it is more than just blowing into a mouthpiece and your wiggling fingers. Just like playing the piano is more than playing the black keys on a piano. Making music on a NAF is also about breathing, phrasing, good hand positioning, listening and having a solid playing technique.
Just like someone wanting to start playing the piano will find a teacher, having a qualified teacher for the NAF will help you play your instrument with confidence and comfort. A teacher will help you to develop your skills in a safe, non-judgmental environment, enabling you to reach your full potential as a Native American style flute player. This is true even if you've chosen to play the NAF for simple relaxation. How relaxing is it to squeak, run out of breath, feel like your playing is always the same or be nervous playing for friends or family?
Taking lessons from a teacher, even short term, can also help prevent you from making frustrating mistakes, developing long term bad habits, (that are hard to break) and give you the guidance to move forward when you feel stuck.
One of the most common bad habits is poor hand and finger positioning. The majority of players I encounter have this problem, and they are not even aware of it. People who hold their hand wrong don't feel comfortable with their instrument. They feel hesitant, miss holes and squeak frequently. This leads to frustration, a lack of confidence, and a lower level of enjoyment with their playing. If caught early this can be corrected. If not, it can become a very bad, hard-to-break habit. A good teacher will spot this problem, and help you develop good hand and finger techniques to allow you to play with confidence and increase your speed.
Another problem many NAF players have is not breathing correctly. The NAF is a wind instrument and if the player does not know how to breath properly, they run out of breath in the middle of phases, squeak, play out of tune and their tone can sound "sour". Breathing correctly in order to play a wind instrument is a skill that needs to be developed. Running out of breath is no fun. A teacher can help you with the skill of good breathing.
Maybe you took up the NAF to create songs? Just like composing on a piano, you wouldn't expect someone with no training to sit down at a piano and suddenly create music. The songs you hear every day are produced and created by people who have learned the basics of song creation. The basic concepts are not hard or complex, but if you have no training you will be unsure how to start and, at best, waste time reinventing what others already know. A teacher can show you these simple concepts, helping you create songs from even the smallest musical fragment, and guide you when you feel like you are stuck.
In my teaching I have had many students say to me, "I never knew how that was done", or "I never knew that was possible, until you showed me." And it makes sense. How do you know what you don't know? A good teacher, with a solid background in music, can take you far beyond what holes to cover, enabling you to free the music inside you.
Take control of your playing, a teacher will help!
