to the string to give it a deeper bass note the
12
strings for a grand piano range in length from just five centimeters to over two meters.
13
That's what allows them to produce an incredibly wide range of notes.
14
Finally, he tightens the end of the wire to stop it from uncoiling.
15
They have to use layers of flexible wood for the piano's casing, so they'll be able to bend it into the traditional shape.
16
They're glued together and then squashed in a press until the adhesives dry.

Then it's taken over to another press which will give it its shape.
18
It's a tough job to get it into position and requires a bit of muscle and a lot of teamwork.

30
so they produce an even sound.
31
A key has to drop under a weight of 52 grams, and they all have to be tested one by one.
32
Who said the music industry was glamorous?
33
All that remains is the final assembly.
34
Every individual grand piano is handcrafted to the highest standards.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
