Inside the Piano Factory – How Upright and Grand Pianos Are Built From Wood to Music

Описание: How does raw wood and metal hardware become a *grand piano or upright piano* capable of filling a concert hall with music? 🎹🎼 In this video, we go *inside the piano factory* to show *how upright and grand pianos are built from wood to music**, following the **full manufacturing process* from lumber and cast-iron frames to final tuning and play-testing. 🏭✨

You’ll see each key stage of the **piano manufacturing process**:

*Step 1 – Wood Selection, Seasoning & Rim/Case Construction*
Carefully selected *spruce, maple, mahogany and other tonewoods* are dried, seasoned and shaped into the *rims, backs and cabinets* of both upright and grand pianos, forming the structural heart of the instrument. 🌲

*Step 2 – Soundboard, Bridges & Cast Iron Frame*
Precision-cut *spruce soundboards* and bridges are installed, then a massive *cast-iron plate* is mounted to withstand the tension of hundreds of strings. This step defines projection, resonance and stability.

*Step 3 – Stringing, Pinblocks & Scaling*
Technicians install **tuning pins, steel treble strings and copper-wound bass strings**, following a carefully engineered scale design that determines **tone, power and tuning stability**. 🎵

*Step 4 – Action Assembly & Keyboard Installation*
Thousands of small parts are assembled into the *piano action**: hammers, shanks, levers and dampers working together under each key. The **keyboard and action* are installed and carefully aligned for a responsive touch.

*Step 5 – Regulation, Voicing & Fine Tuning*
Specialists *regulate* key travel, hammer distance and repetition, then *voice* the hammers to balance brightness and warmth. Finally, each piano is *tuned repeatedly* until it meets professional musical standards. 🎹

*Step 6 – Final Inspection, Polishing & Shipping*
Cabinets are polished, pedals and hardware are checked, and the entire instrument goes through *strict quality control* before being packed and shipped to *homes, studios and concert stages* around the world. 🌍

From *rough lumber and metal* to *concert-ready upright and grand pianos**, this full-process factory tour shows how **engineering, craftsmanship and musical precision* work together inside the **modern piano factory**.
