About the music works

    • Go to our catalog and select the work you want to play: whether it is an opera aria, a movement of a concerto or a complete concerto, you can get the conductor and instrument scores and music of all the individual instruments, and the full orchestral ensemble.
    • Open the work you bought in the Synchestra-app. Set your own tempo and tempo changes, or make the orchestra follow your tempo and tempo changes, change the pitch and transposition to accommodate your own instrument or voice capabilities.
    • Start playing with the orchestra & enjoy!
  • Please make sure that you visit our catalog page.

  • We welcome suggestions! If there’s a composition you’d like to see in our repertoire, contact us at info@synchestra.ai.

    • We input every paper score into the computer with clever OMR (Optical Music Recognition) software. This OMR software does not work perfectly, by the way; it always requires manual work. And sometimes, if there is no other way, we write note by note manually.
      This way, we get a digital version of the score.
    • Then we orchestrate, instrument by instrument. Here we are actually doing what the conductor does during orchestral rehearsals.
      A monk's work, in other words. To give you an idea: Three years ago, it took us three months to digitise Tchaikovsky's first piano concerto, starting from the 1892 edition and the 1876 manuscript. And orchestrating is also a long patient process.
      Crazy work. Yet we do it.
      Because we are passionate about music. We are inspired and enthousiastic. And perhaps also a little crazy, yes.
      And because we have a dream.
    • Finally, the work is packaged in a production file that can be downloaded by the customer.
  • Synchestra wants to bring the orchestra to you. That's why we focus on works written for solo and orchestra:

    • compositions for one or more soloists and orchestra: concertos, double concertos, triple concertos, concertos for four soloists and orchestra
    • forms related to concertos: rhapsody, concertante rondo, concertante fantasia, capriccio, sinfonia, etc.
    • arias from opera, operetta, oratorio, requiem, mass, cantata, symphony
    • songs for voice(es) and orchestra


    In short: we are aiming for works that require at least 5 musicians. What we do not include in our repertoire, for example:

    • chamber music for limited ensemble: duos, trios, quartets;
    • songs for voice and piano, or voice and basso continuo.


    We concentrate on music in the public domain. That is music of which the composer has been dead for at least 70 years (in Canada it is 50 years, in the United States 100 years).

    Because after that period, no royalties are owed to the composer or his heirs. Not that we don't want to pay royalties. But negotiations with composers or their rights holders are often complicated and time-consuming. In the start-up phase of Synchestra we prefer to put our time and energy in other things.

    Don't we want to bring contemporary music? Yes, we do.

    If a composer would like to make their work(s) available through Synchestra and would like to become a member of our Community, this is possible. We are very happy to do so!

  • No! You can play our works with any instrument of the orchestra.

    Example 1: We have a concerto for violin and orchestra. There is a Violino Principale, and there are also the Violino sections I and II, possibly each divided in divisi a and divisi b. You can chose to play each of the these different parts, in this example five parts: the Violino Principale, Violino Ia, Violino Ib, Violino IIa, Violino IIb. You can study, rehearse and play them separately. If you play in a Violin section, you can decide to mute your section, or to lower the volume of that section to play along with that section, or even increase the volume of that section to get the feeling that you are sitting next to them.

    Example 2: If there are 4 horns in the orchestra, you choose Horn I, II, III and IV separately.

  • Yes. In that case, you will let the violin solo play all the way with the orchestra, and you will chose to play oboe I, oboe II, the oboe d'amore, or the English horn. You can mute each part independently, and you have the score parts of each separate instrument. And the conductor score of course!

  • For all our compositions, we try to stay as close as possible, historically and musicologically, to the original intention of the composer. Therefore:

    • Wherever possible, we start from a "Urtext" edition or from a Critical Edition. This is a version that is as close as possible to the composer's manuscript. (If it still exists, that is.)
    • We offer the works in their original version, with all the instruments that the composer originally intended. So we do not present any orchestral reductions.
    • We also respect the original performance notation and fingering (if any) of the composer.
    • We do not add fingerings that were not written by the composer.
    • We do not add tempo or metronome markings that were not added by the composer.
    • If we nevertheless find it necessary to make additional markings, we will put them (in brackets) and/or note them with dotted lines --- . For example, in the case of a legato bow, when it is not certain that it was written by the composer.
    • We also correct obvious writing errors, for example those made by a copyist (when the original autograph got lost), or when a note in the conductor score is clearly different from the corresponding note in the instrument part, or when the composer wrote an obvious mistake (yes, that happens).


    We stay as close as possible to the historical version, but we do take modern performance practice into account. 

    Mozart, for example, originally wrote his clarinet concerto KV. 622 for the basset clarinet. This instrument was a novelty in its day, but is hardly ever built nowadays. That is why we offer this clarinet concerto in two versions: for the basset clarinet and for the common clarinet.

  • We make sure we are respecting the intellectual rights of all our contributors:

    • We focus on compositions that are in the public domain.
    • For recent compositions, we make sure we have the authorisation of the composer or his rightsholders.
    • The composers (if applicable), scorewriters, proofreaders and orchestrators receive author rights payments for their work.


    Should someone think their copyrights are being infringed, we ask to contact copyright@synchestra.ai, to resolve the matter.

General questions

  • Becoming a Patron is the best way to directly contribute towards the creation of a new work. Depending whether you are interested in becoming a Silver, Gold or Platinum Patron, the contribution and reward vary.

    Check out our Patron page

  • Synchestra has a clear mission: We want to make benefits, but only to make our company sustainable and long-lived. As we grow, those benefits are re-invested into the company (and not distributed to the shareholders), to improve the app, and to expand the portfolio. This means you’ll not only gain access to an ever-expanding repertoire but also enjoy an increasingly enriched experience.

    The wealth of our company is not the amount on the bottom line of the yearly accounts, but the total amount of happiness of our musicians who enjoy playing beautiful music with our app.

  • Yes, Synchestra is an excellent tool for music educators. Teachers can use it for individual or group practice, offering students a virtual orchestral experience.

  • Yes, you are welcome to share recordings of your performances using Synchestra. Please credit Synchestra in your posts, and tag us to help spread the word!

  • Yes! Follow us on social media, subscribe to our newsletter, and join our forums to connect with other musicians and share your experiences. And please subscribe here!

  • We dream of having as many musical works as possible in our app, so that musicians from all over the world can play the works of their choice with a real orchestra.

    We are working hard to speed up the scoring and orchestration processes: for example, today that Tchaikovsky score would take a month instead of three.

    We dream of a Community of passionate music lovers, of freaks like us who love to digitise paper scores. And who enjoy spending days orchestrating them. Purely out of love for music.

    We dream of a Community of musicians - students, professional musicians, music teachers, choir members, conductors, ... - who are willing to pay a democratic price for a piece of music from our app. So that we can continue this work and pay out a small sum to those fanatics who spend months lonely in their attic room digitising and orchestrating scores.

  • Do you know how to write a digital orchestral score with Dorico Pro (that's our standard music notation software)? Then you are a valuable asset to the Community!

    What we expect from you:

    • You can demonstrate some relevant experience with the more serious orchestral work for classical music. For example, a composition for a dozen instruments, or more.
    • Having written the score for a piano sonata or a choral work is really not enough, we're afraid.
    • You can demonstrate this experience by sending us some conductor scores in PDF and (preferably) .dorico format, or by providing a link where we can admire your work.
    • We expect you to be particularly meticulous and to faithfully copy, in addition to the correct notes of course, all of the composer's original indications (musical arcs, forte/piano indications, tempo changes, performance techniques, etc.), excluding anything the composer has never have written.
    • Therefore, we always start from an "Urtext" edition, if possible. We will help and advise you in choosing the best reference editions when you start working on a specific composition.


    Know more about scorewriters

  • Can you convert the MIDI output of classical music orchestra scores into music project files, for example using a Digital Audio Workstation (DAW) with sequencer software such as Steinberg Cubase, Apple Logic, Ableton Live, Presonus Studio One, Cockos Reaper, Studios Reason, Steinberg Dorico, etc.? Then we would love to have you as a community member!

    What we expect from you:

    • You can demonstrate some relevant experience with classical music compositions using advanced virtual instruments.
    • You know how to introduce humanisation effects into classical music renderings.
    • You can demonstrate this experience by sending us audio files (MP3 at 192 kbps or better, or any other high quality audio format, if possible lossless), or by providing a link where we can admire your work.
    • We expect you to aim to make orchestrations of such quality that an experienced musician either cannot distinguish your work from a real studio live recording, or at least hesitates seriously about it.


    Know more about orchestrators

  • The "Hall of Fame" is a special part of Synchestra’s website where we honour and celebrate our Patrons. It’s our way of showing appreciation for those who support our mission, giving them a lasting place of recognition for their contribution to bringing music to life.

Purchasing and licensing stuff

  • The complete catalog has been curated carefully and submitted for review to professional scorewriters, orchestrators and a jury so that only high-quality works are on offer. This effort is bigger for a long concerto than for a small opera aria. Therefore, based on actual effort a different price is tagged to each work.

  • The music works will be available in two functional modes:

    • a basic version, with a very affordable price
    • a full version = basic version + a lot of extra functionalities; this comes with a price premium of about 50%.


    The price for a specific work depends essentially on the length and its complexity (it is less manual effort to produce an aria of 5 minutes with a chamber orchestra, than a 30 minutes concerto with a symphonic orchestra).

  • Yes. You will pay the upgrade price. Please note that it is cheaper to buy directly the full version, rather than doing the purchase in two steps, because you will save on administration and financial transaction costs.

  • Currently, we accept euro and US dollar. You choose.

  • Because we must apply different VAT (sales tax) rates according to your country of residence. Within the European Union, VAT rates for our products varie between 0% and 25%. Outside the European Union, the VAT rate is 0%.

  • Our prices are established in euro, and prices in other currencies are converted using daily exchange rates and currency exchange costs. For that reason, our euro prices are not changing on a daily basis, while the price in other currencies may fluctuate over time.

  • Yes, we create an invoice for each purchase. For that reason, we need to know your name, and address, to apply the taxes that are applicable to your country of residence. If you need it for professional purposes, please indicate also your VAT number (if applicable).

  • Yes, as long as the licence hasn’t been activated yet. You can use the musical works, or the access pass yourself, but you may also transfer them to someone else: your child, a family member, or a friend. Please note that you can only transfer your purchase to one physical person, and only if the licence has not yet been activated.

  • When you buy a specific work, you receive a product activation code.

    • The product activation code is needed to validate the licence (authorisation) to use that specific work.
    • This code can be used by you, or any other person you choose (your child, a friend, a colleague, ...).
    • However, the code can only be used by a single person.
    • When a person activates the code, they become the only musician who can use that particular licence code.
  • When you activate a product activation code for a specific work:

    • You can start using and enjoy that work for the rest of your life.
    • You can use the corresponding licence on three different devices (e.g. desktop pc, tablet, smartphone).
    • You can transfer the license from an outdated (or lost, stolen) device to a new device.
    • Please note: the license is granted to you personally. You cannot share the license with a family member, a friend or a colleague.
