SAP Alaudis is an extraordinary piano created to capture the enchanting beauty and sound of the skylark’s song. It was born from the desire to craft a masterpiece instrument – one that captivates with its tone, stirs emotion, and becomes a natural extension of the pianist’s soul.

The Alaudis piano is the result of human hands, patience, and a deep love for sound. We do not rely on mass production – every instrument is built individually, in an atmosphere of focus and perfection. Each element – from the soundboard, bridges, and action to the finishing and voicing – is crafted with the utmost attention to detail.

Our goal is not merely to build a piano, but to create a work of art – an instrument with a soul that inspires both pianist and listener alike. In Alaudis, we unite classical craftsmanship with modern acoustic innovations, creating a sound full of depth, warmth, and life.

It all begins with wood. At first glance, they are just ordinary boards, stacked and waiting for their moment – the moment when they will transform into sound. Within them lies the future soul of the piano.

At SAP Alaudis, we choose wood as an artist selects colors for a painting. We search for harmony, flexibility, and spirit within it. Each species has its own voice – resonant spruce brings warmth and depth, birch adds precision, while maple and beech provide strength and durability.

For years, the wood matures in natural conditions before it reaches the hands of our craftsmen. Only then does the true transformation begin – from raw material into a carrier of emotion.

Because a piano is not a machine.
A piano is wood that sings.

The body of SAP Alaudis is made from several-millimeter veneers of carefully selected birch and maple. This combination provides the perfect balance – the flexibility and resilience of maple, and the stability and strength of birch.

Each layer is arranged according to the grain direction, then glued and bent on a special mold – the “kopyto” form. Under controlled pressure and temperature, the veneers merge into a single continuous rim that retains its shape with absolute precision.

Such a laminated rim offers exceptional structural rigidity, minimizes internal tension, and increases tuning stability – while still allowing the body to actively resonate with the soundboard.

The result? A rim that not only supports and unites the instrument, but also co-creates its tonal character — perfectly reflecting the Alaudis philosophy: A piano is wood that sings.

At SAP Alaudis, we selected Okoumé wood for the production of our piano lids because of its exceptional balance of lightness, stability, and resonance. Okoumé allows us to create lids that are lighter than traditional ones while maintaining a multi-layered structure. This layered construction reduces internal stresses, enhances dimensional stability, and increases the component’s longevity. Such a design brings tangible benefits: reduced load on the hinges and mechanism, easier lifting of the lid, and greater overall comfort in use. It also carries acoustic advantages – lower mass means less “dead” structure that could otherwise absorb vibrations. Unlike heavy, rigid constructions, we strive for harmony: a premium material combined with fine craftsmanship to create an element of comfort that never limits

The finishing of the SAP Alaudis piano has been carried out with the utmost precision. We used the coating system by ICA – a renowned Italian manufacturer of finishes dedicated to musical instruments.

Six layers of primer were applied to the body and cabinet parts, then cured for 350 hours to ensure deep substrate penetration and stable base layers. Next, nine layers of polyester topcoat were added and cured for 400 hours, guaranteeing exceptional gloss, scratch resistance, and long-term durability.

This multi-layer finishing process results in a smooth, deep, mirror-like surface that not only enhances the piano’s aesthetics but also protects its structure from humidity changes, UV radiation, and mechanical damage.

Thanks to this meticulous finishing, the SAP Alaudis piano combines timeless elegance with lasting protection, ensuring perfect technical and acoustic condition for many years to come.

SAP Renovation is one of Europe’s leading specialists in piano finishing. Over the past three decades, our team has restored nearly 14,000 instruments – more than 10,000 of which received a high-gloss polyester finish, ranging from concert grands to historic models by Steinway, Bösendorfer, and Bechstein.

At SAP Renovation, the sanding and polishing process combines master craftsmanship with modern technology. For the SAP Alaudis piano, this process was carried out with exceptional attention to every minute detail.

After the successive layers of coating were applied, a multi-stage sanding cycle was performed until an ultra-smooth surface was achieved, followed by an intensive polishing phase that produced a flawless, mirror-like finish.

The final surface of the SAP Alaudis piano not only impresses with its shine and beauty but also forms an integral part of the instrument’s structure – minimizing vibration loss, reducing micro-resonances, and supporting acoustic transmission through precise optical reflection and mechanical coherence of the finish.

The soundboard of the Alaudis piano is made of tone-grade spruce supplied by the renowned manufacturer Strunz and serves as a key component of the instrument’s acoustic structure. It is often regarded as the heart of the piano, as it determines both the power of projection and the tonal character. Carefully seasoned and selected wood, precisely fitted to the body frame, forms an active resonating surface that transmits and amplifies the vibrations of the strings, giving the sound its richness, wide harmonic spectrum, and long, natural sustain. Designed in the spirit of the finest piano-making traditions, the soundboard provides the instrument with full tonal projection and perfect balance – from deep, rich basses to clear, transparent trebles.

The Alaudis bridges are made of carefully selected hard maple, seasoned and moisture-stabilized according to the standards of the finest piano manufacturers. Their laminated construction, composed of vertically glued layers of hardwood, is additionally reinforced with a solid maple cap, ensuring outstanding mechanical stability and long-term tuning durability.

This design provides high longitudinal stiffness, allowing the energy of the vibrating strings to be transmitted to the soundboard with maximum efficiency. The reduced contact surface between the bridges and the soundboard enables the latter to vibrate freely, supporting long sustain and a rich harmonic spectrum.

Precisely cut string notches at the points of contact guarantee optimal vibration transmission and tuning stability. Every aspect of the bridge design has been engineered to achieve full tonal projection and perfect coherence – from deep, resonant basses to the purest trebles.

The pinblock of the Alaudis piano is made of cross-laminated, multi-layered beech plywood, constructed according to the principles used in the world’s finest pianos. Its layered structure, oriented along alternating grain directions, provides exceptional mechanical stability and resistance to humidity changes and string tension stress. The cross-grain layout – following the Hexagrip concept, where each layer is rotated by 45–90 degrees – ensures uniform pin torque and minimizes the risk of cracking, resulting in greater tuning stability over time. In practice, professional beech pinblocks typically consist of around 21 laminations with a thickness of 1 3/8″, providing secure torque retention even under total string tension exceeding 18 tons (~40,000 lb). Thanks to this construction, the tuning pins remain firmly anchored, guaranteeing long-term tuning stability and ideal transmission of energy from the strings to the resonant structure. The entire system is designed to preserve precise intonation while maintaining a sound that is rich, stable, and highly accurate.

The cast-iron frame of the Alaudis piano has been designed according to the highest structural standards of the world’s finest piano manufacturers. The casting is made of high-grade grey cast iron, engineered to withstand the mechanical stresses generated by the string tension.

Thanks to precise casting and meticulous finishing, the frame serves not only a structural function – stabilizing the entire instrument – but also an acoustic one, maintaining optimal contact between the string-bearing section and the body of the piano. Carefully engineered reinforcements and accurate integration of the frame with the case allow for the full transmission of string energy, ensuring powerful sound projection and tonal clarity across the entire range.

As a result, the Alaudis frame acts both as a durable structural stabilizer and as an active acoustic partner, enabling the instrument’s entire construction to work freely and efficiently.

In the stringing of the SAP Alaudis piano, we use Diamant tuning pins (Julius Klinke, Germany), renowned for their precision manufacturing and consistent parameters, which ensure stable torque and reliable tuning retention.

The set of steel strings is made from Röslau wire, valued for its uniformity and excellent elastic properties, while the bass strings are supplied by Hellerbass (Germany), a company specializing in precision-wound bass strings for piano manufacturers and restorers.

The string scale was designed using dedicated calculation software that optimizes diameters, speaking lengths, and target tensions, taking into account inharmonicity and the desired tonal characteristics.

In the SAP Alaudis piano, the precise compatibility between the wire, tuning pins, and scaling parameters is essential to ensure perfect balance with the strength of the frame and the overall structural integrity of the instrument.

The keyboard of the SAP Alaudis piano was developed in close collaboration with Kluge, one of the world’s most respected manufacturers of premium piano keyboards. A custom design was created exclusively for SAP Alaudis to ensure that the keyboard perfectly matches the instrument’s concept – serving as a natural extension of the pianist’s artistic expression. Crafted by Kluge, the keyboard provides exceptional acoustic and mechanical balance, with minimal damping of the instrument’s vibrations in the keyboard area. This allows for full sound transmission and ensures stable, responsive performance. The construction also reflects refined aesthetic detail: perfectly aligned keys, flatness within millimetric tolerance, softly rounded edges, and immaculate surface finishing –all emphasizing the instrument’s luxurious character. As a result, the SAP Alaudis keyboard is not merely a mechanical component but an integral part of the pianist’s artistic voice – responding precisely to intention, enabling nuanced control, and supporting the full tonal richness that the instrument offers.

The voicing of the SAP Alaudis piano is one of the most demanding stages of the finishing process – the moment where technique meets art. The purpose of voicing is to give the instrument its individual tonal character through precise adjustment of the hammers, felts, and the hammer-string contact point.

Each hammer is individually shaped and voiced. Using needles and specialized softening or hardening solutions, the technician adjusts the elasticity and density of the felt to achieve the perfect balance between attack and tonal sustain.

This process requires exceptional experience – hammers that are too hard can make the sound excessively bright or metallic, while those that are too soft reduce projection and clarity. At SAP Alaudis, voicing is carried out in several stages: after the initial regulation and voicing, the piano undergoes a playing-in process using an automatic player system, followed by a final fine regulation and a second round of precise voicing.

The result is a tone with a full harmonic spectrum, perfect register balance, and exceptional singing quality – characteristic of the skylark. The voicing of the SAP Alaudis gives the instrument its unique identity while preserving the natural warmth and richness of tone that form the essence of our sound philosophy.
