The electric bass is one of the many instruments that emits low frequency sounds, the low sounds, those that, if properly amplified, make the walls and floors vibrate.
The frequency range of the lows, in broad terms, from about 16-20 Hz (at the limits of the audible) to 600 Hz (considering in this way also the medium-low range), in a strict sense we could reduce this range from about 30 Hz (the low B of a 5-string bass) to 100 Hz (more or less the G, the I string – the one with the highest pitch – in a 4-strings bass), in practice imagine the left-hand side of the keyboard of an organ or a piano (the central part instead emits the medium frequencies, the right-hand side the high frequencies).

The main role of low frequencies is to provide rhythmic-harmonic support to musical pieces, in an even more technical way we can say that its function is to create and emphasize harmonic movement with a melody performed precisely with low-frequency notes.

Terms like rhythm, harmony and melody have appeared, the three fundamental structural elements of music, let’s try to get to know them better one by one.
