Marine Band 364/24 Soloist differs from the tools in this series only in formation. The design and timbre are the same as those of 365/28 and 364/24. The peculiarity of the system is that in a row in all three octaves the gamma in C major is laid. At the same time, the notes are arranged so that when you inhale 1,2,3,5,6,7,9,10,11, the holes sound like D minor triad, and all the holes on the exhale sound like C major. It is possible to take bends and blows, thus the chromatic scale appears. The model is quite suitable for playing both blues and melodic compositions. The tool is based on Marine Band 364/24. Marine Band Soloist is a diatonic harmonica with a 12-hole chromatic harmonic system, but without a slider.
