Get a diatonic harmonica in the key of C to start. C is the key of the beginner harps here, and a 10-hole diatonic in C covers blues, folk and rock. A harmonica in a different key, like the Hohner in D, plays in that key instead.
Start with a diatonic in C
A diatonic harmonica plays in one key. C is the key to start with: the Fender Blues Deluxe, the East top and the EastRock are all 10-hole diatonics in C, and each one is made for beginners. The Fender has brass reeds, and the East top and EastRock have phosphor bronze reeds. The Hohner Special 20 is in D, so it plays in a different key. Buy one key to start, and add a second key later.
Match the key to the music
The key on the harmonica should match the key of the music you play. A C harmonica plays in C, so it fits music in C, while the Hohner in D fits music in D. If you play with other players, ask what key the music is in and bring the harmonica in that key. One harmonica covers one key, so players who play in more than one key keep more than one harmonica.
Check the reeds, comb and case
Reed and comb materials differ across these harmonicas. The Fender has brass reeds with a molded PVC comb, and the East top has a phosphor bronze reed with a plastic comb and a 1.2mm reed plate. The EastRock has phosphor bronze reeds with food grade ABS resin combs and a stainless steel cover. The Hohner has a smooth plastic body with responsive reeds. The Fender, East top, EastRock and Hohner each come with a case.
Check the warranty and size
The Fender and the East top each carry a 1 year warranty, and the Hohner carries a 90-day warranty. The East top measures 4.01 by 1.06 by 0.75 inches and fits in a pocket, while the Fender set with its holder measures 11.42 by 7.48 by 3.54 inches. The EastRock and Hohner each come with a case, so check the size of the case against your pocket or bag before you buy.
