The chromatic harmonica is a type of harmonica that uses a button-activated sliding bar to redirect air from the hole in the mouthpiece to the selected reed-plate desired. When the button is not pressed, an altered diatonic major scale of the key of the harmonica is available, while depressing the button accesses the same scale a semitone ...
However, in the majority of other tunings (such as 19-tone and 31-tone equal temperament), there is a difference in tuning between notes that are enharmonically equivalent in 12-tone equal temperament. In systems based on a cycle of fifths, such as Pythagorean tuning and meantone temperament, these intervals are labelled diatonic or chromatic ...
Indeed, the similarities between harmonicas and so-called "diatonic" accordions or melodeons is such that in German the name for the former is "Mundharmonika" and the latter "Handharmonika," which translate as "mouth harmonica" and "hand harmonica." In Scandinavian languages, an accordion is called variants of "trekkspill" (pull play) or ...
A diatonic harmonica is designed to ease playing in one diatonic scale. Here is a standard diatonic harmonica's layout in the key of C (1 blow is middle C): This layout easily allows the playing of notes most important in C major, that of the C major triad: C, E, and G. The tonic chord is played by blowing and the dominant chord is played by ...
The Richter-tuned harmonica, 10-hole harmonica (in Asia) or blues harp (in America), is the most widely known type of harmonica. It is a variety of diatonic harmonica, with ten holes which offer the player 19 notes (10 holes times a draw and a blow for each hole minus one repeated note) in a three-octave range. The standard diatonic harmonica ...
The distinction between diatonic and chromatic intervals is controversial, as it is based on the definition of diatonic scale, which is variable in the literature. For example, the interval B–E ♭ (a diminished fourth , occurring in the harmonic C-minor scale ) is considered diatonic if the harmonic minor scales are considered diatonic as ...
Richter tuning is a system of choosing the reeds for a diatonic wind instrument (such as a harmonica or accordion).It is named after Joseph Richter, a Bohemian instrument maker who adopted the tuning for his harmonicas in the early 19th century and is credited with inventing the blow/draw mechanism that allows the harmonica to play different notes when the air is drawn instead of blown.
Solo tuning is a system of choosing the reeds for a diatonic wind instrument (such as a harmonica or accordion) to fit a pattern where blow notes repeat a sequence of C E G C (perhaps shifted to begin with E or with G) and draw notes follow a repeating sequence of D F A B (perhaps correspondingly shifted).
