Product Overview
The ONE Keyboard Piano Sing is a 61-key digital piano keyboard designed specifically for beginners and aspiring singers who want to learn piano accompaniment. What sets it apart from traditional keyboards is its integrated LED light system that guides users through chord progressions and melodies, making it possible for complete novices to play recognizable songs within minutes.

This instrument comes in an elegant black finish and measures compact enough for home use while maintaining the feel of a larger piano. The keyboard features velocity-sensitive keys that respond to your playing dynamics, providing a more authentic piano experience compared to basic electronic keyboards. The standout feature is its seamless integration with two powerful mobile applications that transform how you learn and interact with music.
Unlike traditional 61-key portable keyboards, this instrument focuses heavily on the singing aspect, making it ideal for vocalists who want to accompany themselves or anyone interested in learning piano through a more engaging, multimedia approach.
Key Features Breakdown
Revolutionary Light-Up Key System
The most impressive feature of The ONE Keyboard Piano Sing is its built-in LED light system. Each key contains an LED that illuminates to guide you through songs and lessons. This visual learning aid is particularly beneficial for beginners who struggle with reading sheet music or remembering chord positions.
The system works in two primary modes: one-finger chord mode for absolute beginners, where pressing a single lit key triggers a full chord, and traditional five-finger playing for more advanced users. This progression system allows users to start playing songs immediately while gradually building proper technique.
Dual App Integration
The keyboard comes with access to two comprehensive mobile applications:
- TheONE Sing App: Focuses on vocal performance with piano accompaniment, featuring hundreds of songs with synchronized lyrics and chord progressions
- TheONE Smart Piano App: Provides structured piano lessons, music theory instruction, and traditional piano learning content
Both apps receive regular updates with new songs and features, ensuring fresh content for continued engagement. The apps include recording functionality, allowing users to track their progress and share performances.

Professional Sound Quality
Despite its focus on beginners, The ONE Keyboard Piano Sing doesn’t compromise on sound quality. It features:
- 256 built-in voices covering various instruments and sound effects
- 64-note polyphony for complex musical arrangements
- High-quality grand piano samples as the default sound
- Dual voice capability for layering different sounds
- Dual keyboard mode for split playing or teaching scenarios
Connectivity and Practice Features
The keyboard offers multiple connectivity options including USB-MIDI for connecting to computers and external devices. The Bluetooth connectivity specifically pairs with the mobile apps (note that it doesn’t support Bluetooth headphones – wired headphones are required for private practice).
For those concerned about practicing at all hours, the keyboard includes headphone output and volume control, making it neighbor-friendly. This consideration makes it suitable for apartment living or shared spaces.

Performance Analysis
Learning Effectiveness
The light-up key system proves remarkably effective for initial engagement and basic chord learning. Users typically experience success within their first session, playing recognizable chord progressions to popular songs. This immediate gratification helps maintain motivation during the crucial early learning period.
However, the transition from light-guided playing to independent playing requires dedicated practice. The apps provide structured progression, but users must commit to regular practice sessions to develop muscle memory and theoretical understanding.
Sound Quality Assessment
The sound quality exceeds expectations for this price range. The grand piano samples sound rich and dynamic, responding well to velocity changes. The 64-note polyphony handles complex arrangements without note-dropping, though it may not match the capabilities of higher-end digital pianos.
The variety of voices adds versatility, allowing users to explore different musical styles beyond traditional piano. The dual-voice feature enables creative layering, though this functionality requires some experimentation to master effectively.
App Performance
Both mobile applications generally perform well, with intuitive interfaces and stable Bluetooth connectivity. Song recognition and tempo adjustment work smoothly, though occasional sync issues may occur with older mobile devices. The recording feature provides clear audio capture for practice review.
Regular app updates demonstrate ongoing developer support, adding new songs and features. The song library spans multiple genres and difficulty levels, ensuring long-term engagement.
Value for Money
At its current price point, The ONE Keyboard Piano Sing offers excellent value for its target audience. The combination of hardware quality, innovative learning system, and comprehensive app content justifies the investment for beginners serious about learning piano and singing.
Compared to traditional piano lessons, which can cost $50-100+ per session, this keyboard pays for itself after just a few months. The self-paced learning approach also eliminates scheduling constraints and ongoing lesson fees.
When evaluating important features for beginner digital piano buyers, this instrument excels in user-friendliness and engagement, though it may lack some advanced features found in pricier alternatives.
Comparison Context
In the 61-key keyboard market, The ONE Piano Sing competes against instruments like the Casio Casiotone CT-S300. While the Casio offers more traditional features and connectivity options, The ONE Piano Sing’s light-up learning system and vocal focus create a unique market position.

For users considering full-size options, 88-key alternatives like the Umomo U-710 provide extended range but lack the innovative learning features. The choice depends on whether immediate playability or long-term expansion matters more to the individual learner.

Frequently Asked Questions
Do I need prior musical experience to use this keyboard?
No prior musical experience is required. The light-up key system and one-finger chord mode allow complete beginners to play songs immediately. The apps provide gradual progression from basic chord playing to more advanced techniques, making it ideal for absolute novices.
Can I use this keyboard without the mobile apps?
While the keyboard functions as a basic digital piano without the apps, its primary value lies in the app integration. The light-up keys, song library, and structured lessons all require app connectivity. Without the apps, you’re essentially using a standard 61-key keyboard with limited built-in features.
How does the Bluetooth connectivity work?
The Bluetooth connection pairs specifically with The ONE mobile apps and is used for controlling the keyboard’s learning features and light system. It does not support Bluetooth headphones or speakers – audio output requires wired headphones or external speakers connected via cable.
Is this suitable for children?
The keyboard is designed primarily for teens and adults due to its app-dependent learning system. While children can use it with adult supervision, younger learners might benefit more from traditional piano methods or keyboards designed specifically for children. The mobile app interface assumes basic reading skills and technological familiarity.
What happens if the apps are discontinued?
This is a valid concern for any app-dependent device. Currently, The ONE Music Group actively develops and updates both apps with new content and features. However, users should consider this dependency when making purchasing decisions. The keyboard would still function as a basic digital piano without app support.
Can I connect this to my computer for recording?
Yes, the keyboard includes USB-MIDI connectivity, allowing connection to computers for use with digital audio workstations (DAWs) and music production software. This feature enables more advanced recording and composition work beyond the built-in app recording capabilities.

Final Verdict
The ONE Keyboard Piano Sing succeeds brilliantly in its primary mission: making piano learning accessible and immediately rewarding for beginners, especially those interested in vocal accompaniment. The innovative light-up key system, combined with comprehensive mobile apps, creates an engaging learning experience that traditional methods struggle to match.
For its target audience – aspiring singer-songwriters, visual learners, and musical beginners seeking quick results – this keyboard delivers exceptional value. The ability to play recognizable songs within minutes provides the motivation necessary to sustain long-term learning commitment.
However, serious considerations include the app dependency and 61-key limitation. Users should be comfortable with technology and understand that many features require smartphone connectivity. Those seeking traditional piano education or planning to advance to complex classical repertoire might find better value in conventional alternatives.
The sound quality, build construction, and innovative features justify the price point for the intended audience. Regular app updates and developer support suggest ongoing value, though future app availability remains a consideration.
Overall, The ONE Keyboard Piano Sing earns a strong recommendation for beginners seeking an innovative, engaging path to piano learning and vocal accompaniment. Its unique approach to music education, combined with quality construction and comprehensive learning resources, makes it a standout choice in the beginner keyboard market.
