MAISTERSTÜCK is a new AI enhanced system for algorithmic composition. MAISTERSTÜCK models all creative layers of a composer's mind and can create music from structural, stylistic, emotional and real-time attributes.

MAISTERSTÜCK is a service oriented API. You can apply for the closed beta here ↗

Virtual Bands

MAISTERSTÜCK can conserve, depict and recompose the characteristics (composition style, lyric style, sounds and playing techniques) of individual musicians (incl. singers) and their interplay in virtual bands.

For Videos

MAISTERSTÜCK can create music in the desired style, with dedicated climax and turning points, for example as a video soundtrack.

For Workouts

MAISTERSTÜCK can create continous music based on a leitmotif (from user or AI generated) with dedicated sections of tempo and density, for example as a soundtrack for workouts.

For my 30 minute workout, create music based on my own Leitmotif with tempo sections 120, 140, 200 bpm.


Real Time

MAISTERSTÜCK can create continous real-time music based on mappable real-time input, for example as your personal driving soundtrack.

For my cruise, create a real-time soundtrack with music in the style of Hard Rock based on Parameters Speed, Acceleration & RPM.



MAISTERSTÜCK can create songlyrics with given song and syllable structure & rhyme schemes and semantic colouration.

(Not so) Frequently Asked Questions

Is MAISTERSTÜCK Machine Learning? A neural network? The end of all musicians?

  • How does MAISTERSTÜCK work?
    MAISTERSTÜCK uses AI technology to model all layers of creativity of a human composer and implements these layers as reusable and combinable software components. MAISTERSTÜCK’s functionality can be accessed via a service oriented API.
    MAISTERSTÜCK makes use of state-of-the-art AI technology, not only in its machine learning parts but wherever it serves the system’s purpose and its users’ demands. For instance, Markov Models are used as a base technology in composition and lyrics writing, and variational autoencoders (VAEs) are applied to increase variation in the system’s outputs on different musical layers, like drumming styles or the way musicians build their arrangements on top of each other’s input.
  • Is MAISTERSTÜCK Machine Learning?
    Our approach is to combine long-standing professional experience in songwriting and music production (as testified by multiple international chart-entries by the composers that work for and with us) with innovative domain-adapted machine learning techniques. Thus, some components of the creativity layers are handcrafted, while others work with patterns that were machine learned from data which we prepared for that task. Users of MAISTERSTÜCK are in control to decide how much they want automated or where they want to intervene in the creative process.
  • Is this Deep Learning from all music out there?
    In its machine learning parts, Maiserterstück learns specific aspects of a creativity layer from data specifically created by us, gathered and prepared for that purpose. For instance, style-typical chord progressions can be learned from available (collected or created) musical notation data into the chord progression layer. Thus, rather than using a “brute force” big data/deep learning approach from all available audio material out there, MAISTERSTÜCK makes an informed selection of data for its machine learning components.
  • What is a “creativity layer”?
    A creativity layer models a specific task that a composer or songwriter needs to tackle when writing, composing and creating music. For example, some creativity layers are concerned with the rhythmical structure (“the pulse”) of a song, other layers take care of the harmonic form, and yet another focuses on lyrics writing. There are layers for the interplay of musicians within a band context, others for adapting song structures to the expectations of specific audiences. Of course, different creativity layers are intertwined, such that the outcomes of one will feed into processes on others or feedback and re-iterate into earlier creativity layers.
  • Is MAISTERSTÜCK re-using existing audio material?
    Everything that MAISTERSTÜCK creates is based on audio sample material which we either completely created ourselves (together with producers who worked for international productions on gold and platinum record level) or have fully licensed.
  • Are you making composers unemployed?
    MAISTERSTÜCK can be used as a stand-alone-system (“compose music for me”), but it can also serve as a tool for composers seeking new forms of inspiration (“make me a suggestion for a variation of that chorus”). Composers, musicians, producers and computer scientists can also contribute components (sounds, models, algorithms) to MAISTERSTÜCK in different layers.
  • Who owns the copyright of the compositions?
    The output of the service oriented API is royalty free and belongs to the user that paid for it, as long as it is not re-sold. Complete productions, like the output of the virtual bands of the Metalverse, are copyrighted to the entity that composes the outputs of MAISTERSTÜCK to a full production.
  • So now computer nerds are in charge of writing music?
    The composers and producers contributing to the different layers of MAISTERSTÜCK participated in chart breaking productions worldwide, and worked for and with the biggest record companies, cinema production studios and game development creators. Their input is the base for any creative process that builds upon that.Thus, musicians remain in charge of shaping MAISTERSTÜCK together with software developers (who sometimes happen to be one and the same person).
  • Don’t you know that a computer system will never be able to fully replace a real great band / singer / drummer / songwriter / …?
    That is true (for now ;-)). And we think it is great. MAISTERSTÜCK can create great music that happily co-exists with all creative human output from the past, present and future.
  • Where are the limitations of the system?
    Most of the current limitations will disappear over time, as we are working on more and improved sounds, styles, models and creativity layers. The hardest part currently is to create outstanding vocals, but we think we are on a good path.
  • Can MAISTERSTÜCK create music / styles that do not exist yet?
    MAISTERSTÜCK is not designed to create scales, sounds, chords or comparable musical elements that nobody ever used before. But MAISTERSTÜCK can re-combine all existing elements in countless ways, and this can lead to styles and sound experiences that do not exist yet.

  • What are you working on next?
    We are going the full path to virtualizing bands and musicians, including their characters, their social media appearance, their live-on-stage acting and much more.
