Over the centuries they have discovered the tin used to produce various metal alloys used to cover other metals and to protect them from corrosion by mixing copper with tin, then the 'Bronze Age' appears, which in ancient Egypt the bronze began to be used around 3,200 BC for tools and weapons, the tubes that will turn musical instruments will appear later. Today they bind metals with niobium in which 90% is located in Brazil.

Possibly the trumpets were the first instruments of metal alloys. After human understanding of the harmonics, there are trumpets, smaller trumpets that will take more than 1500 years until the end of the XIX century, when the understanding of physics begins to be definitely understood and ordered in a concept and writing totally different from those we were accustomed to writing sacred books and bibles. Physics from which arised the pistons, valves and rod that we use today.
'Beethoven' to do a small scale on the horns had to use a horn and C and another in F, when the musicians were back to make sound the few notes that each had, by the way, is it because today we have instruments in Bb, Eb, F, A and C and we have to learn the hard task of transposition, therefore, changing the text in old scores would take more than a century and the timbre in Bb is different from C, to play Bach we use the trumpet in C, but in Jazz the Trumpete in Bb has another timbre, another DNA.

Anyway, while a discovery isn't made, things do not evolve, only after the invention of electricity comes the lamp and only after the light of the lamp that Edison invents the kinetoscope and the silent film explodes on the large screens, while some claim to have been invented by the French 'Léon Bouly' and mastered by the Lumière brothers at the end of the 19th century, but in this war of patents and lies each has its own truth, as happens with airplane, telephone. Today we know that the metronome of Maelzel is not his, that is, the metronome was never German, Mälzel was Dutch and stole the project of another Dutch 'Dietrich Nikolaus Winkel', although a kind of metronome was found long before in the inventions of the Andalusian 'Abbas ibn Firnas' (810-887).

Only after the electricity that the electric guitar takes the old violin from the hands of young people, from there arise valves for radio and tvs, until amplifiers and Hamond.

Imagine how many musical instruments have ceased to exist in these last two millennia, I think the worst ones have been rejected by those who win by the true administrators of the world, most of us, opinion of the majority that always wins in history and will never be different until it destroys the last moral concepts of the retrograde ones, being that the societies are formed by the whole, and who makes laws never produces nothing, and we have seen dictators literally losing the head.
Then the use and disuse of tradition, are like thick swords stuck in solid rocks, like magic it will never be removed. So it was the Bagpipes, which was feverish in all countries in the middle ages, and lost its post to the accordion, Bagpipes which if not used in by Scots in their military marches, would be today on the side of the Greek Aulos in museums.

This book is pure physics and entertainment, it can be used to teach from children to college students, but as our time is electric power, something new will emerge from there, so we can't be limited and don't consider 'Smart Phones' with music applications as something disposable, but with being the continuation of all that we have heard throughout human history.
