There are two main types of harmonicas, the chromatic harmonica and diatonic harmonica (sometimes called a blues harp). Although the chromatic harmonica is extremely versatile, the harmonica which is predominantly used in blues, rock, country, folk, etc. is called the diatonic harmonica (blues harp).
The diatonic harmonica, or blues harmonica as it is commonly called, doesn't have easy access to all the possible notes like the chromatic harmonica, but many of the notes that are not naturally found can be acquired by "bending" certain draw (inhale) and blow (exhale) notes. It is the 'bending sound' of the diatonic harmonica which attracts most people to it.
Blues harp,cross harp,gob iron and blues harmonica are all terms that different people may use when referring to diatonic harmonicas. The names may be different but the type of harmonica is the same.
