The blues scale is achieved by adding the note between the third and fourth notes on the pentatonic scale. ![]() These frequencies are provided to the resonant open tube in which some of them are attenuated and some amplified based on tube parameters (where the length and cross section area are the most decisive parameters).īy a combination of many free reeds and resonant tubes the diatonic harmonica is given. Playing notes on the 'blues scale' in any key will give you a blues sort of sound. (see the link) and intensity of the excitation mechanism: the velocity of blown air. The frequency (or frequencies - there would be more then one peak in frequency domain) of such an opening mechanism is given by the cantilever paratemetrs such as stiffnes, mass, surface, length etc. The instrument will be slightly off centre, that is how you want it. The library recordings are made with high-quality recording equipment to capture a tremendous closeness of the natural sound of each instrument. Comb A diatonic harmonica comb with a separate chamber for each reed. Often used to refer to the harmonica itself, as opposed to a chromatic harmonica. In this great expert series, we focus exclusively on the recording of live instruments and vocals, all recorded by professional musicians. This is the tuning for normal 10-hole 'short' harmonicas, also called diatonic harps. ![]() Now look straight into the mirror and slide the harmonica so the the 4 hole is directly under your nose. With Harmonica 1 we present another release from the Artist Series of Image Sounds. Put the holder around your neck, stand in front of a mirror and insert the harmonica. Which opens and closes the tube - hence the pressure and velocity variations. Adjusting the harmonica holder Put your guitar aside for now. The free reed could be modeled in the first (and pretty good) approximation as an oscillating cantilever beam. This is actually what is happening with the sound of just about any instrument. The basic model for the harmonica is an open tube as a resonator and an oscillating free reed as a driving mechanism. Regardless, playing two tones of different frequencies at the same time can sound like a chord (i.e., two notes) or they can sort of blend together in your head and sound like a single frequency with an overtone, which causes it to change the character of the sound.
