  Consider your skill level. If you're a beginner and can't read music, choose a diatonic harmonica. Diatonic harmonicas have 10 holes and are individually tuned to a specific musical key so they can make a beginner sound good fast. Most blues players use the diatonic harmonica and learn how to bend notes, creating that bluesy sound. If you're skilled at reading musical notation, a chromatic harmonica, one with all the notes in a scale might be a good solution for you, but it is not as easy to bend notes.

  Consider how much money you want to spend on your harmonica. Harmonicas are less expensive than many other musical instruments, but the price can vary. By law, you cannot try a harmonica in the store before you purchase it. You will have to take a leap of faith and buy then try a few blues harps before you commit to a certain brand. Realistically, you can start your collection for $15 to $60. Over time, you will find out which ones fit your mouth best and produce your favorite sounds. Add more harmonicas to your collection as you grow in musical ability.

  Decide whether you want a to buy a newer or older brand of harp. According to Harmonica.com, the Hohner 560/20 Special Marine Band Harmonica is a musician's "workhorse." There are hundreds of types to choose from in the Hohner brand line. Other brand-name harmonica makers are Lee Oskar, Huang and Suzuki, to mention a few.
  
  
• 4). Choose one or more harmonicas to suit the key or keys you will be playing in. If you're just starting out, you might just want to pick up one harmonica in the key of C to play as you learn since it plays in the mid-range, according to Harmonica.com. Many blues songs are performed in the key of A, so you might want to pick up a harp in that key too. Later, when you're playing with a band, you'll need a collection of harmonicas to suit the key the song is performing in.
  
  
• 5). Replace your harmonica when the reeds become full of spit and sweat and get funky, since replacement reeds are often as much as the cost of a new harmonica.
