The harmonica is capable of producing both notes and chords. A note is the sound produced by inhaling or exhaling on any one hole of the harmonica. A chord is a combination of three or more notes played together. In some situations it is desirable to play two notes together. This is called a double stop. Each of these possibilities require a different technique to produce the correct sound. These different methods will be dealt with as the book progresses. The easiest thing to play on the harmonica is a chord. To locate a particular three hole chord, simply place your mouth at the center note of the chord, allowing your mouth to cover a comfortable amount of the harmonica. For example, to play a chord using the 4, 5, and 6 holes, center your mouth on the number 5 hole. The number 4 and 6 holes will automatically be included. If you are unsure what holes you are covering, try placing your tongue in one of the holes, then replace it with your finger and have a look to see which hole it is. After doing this a few times you will soon become familiar with which holes you are sounding.
The first example on the accompanying recording is a demonstration of chords played with exhale and inhale breaths in the low, middle and high sections of the harmonica.
To imitate what you hear on the CD, start with an inhaled note on holes 1, 2 and 3, followed by exhaled notes and then move up the harmonica, then back down. Don’t worry at this stage about exactly what holes you are playing, just get a feeling for where you should move to produce higher or lower sounds. This first example is not notated, listen to the CD and copy the sounds you hear. As you play, make sure the harmonica points directly into your mouth as shown below rather than being angled. This will allow the air to flow freely through the instrument as you breathe and will produce the clearest sound.
