of an oboe. The 'secret' here is the harmonic (or spectral) content of the waveform. Without going
into hairy mathematical details I will just leave a reference table below:

Finally, another very important characteristic of a sound is the evolution of its loudness. The first
example is the piano. An almost immediate attack, that the percussion of the hammers provokes
on the strings, leave space to a quick 'reduction' of the note's volume in the first few millieconds.
At this point, if the player keeps his finger on the key, the note will slowly fade, otherwise the end
of the sound will come in few tenths of a second. We like to call the shape of the loudness as the
amplitude's envelope.

We briefly defined the characteristics of a 'sound' to be able, in the following chapter, to give an
indication of WHAT kind of blocks could be used to implement those in the real world... Now a
simple link between those characteristics and their implemented building blocks:
