You don't have to do anything other than to know you are now playing in a different key. If you are playing with other musicians, be sure to let them know what key you are in . I'm very eager to learn to play the harmonica, but sometimes I get confused when reading instructions or looking at notes. Take your time, and read over things as many times as it takes for you to understand it. Going over material three or four times is not considered unreasonable when trying to learn a brand new skill.
Many people find it easier to learn, or simply prefer to learn, from live human beings.
You might try calling the local music stores and check to see if there is a harmonica teacher in your area. Yes, but you have to decide that for your self. Practicing in the car, is many times the ideal place and time for busy people to get their practicing and playing in. If you really need to focus on something new, try scheduling 5 minutes before and after your commute where you can just sit in the car and play. Copyright 1999-2001 AYM Music.
