About MusicFlow

What is MusicFlow?
MusicFlow is an online music production service that enhances the experience delivered by media content like videos, slideshows, photos, and games. It provides high quality music that adapts to the mood and feel of every moment of your media content. You select the music you want from our library, the length of the music, and the emotional arc of the music -- and MusicFlow creates a customized track for you.
How is MusicFlow different from other music services?
Instead of searching for the perfect pre-recorded music track e.g. in a stock music library – which you may never find – you can now instantly create your own track, that has the perfect length, music genre and emotional arc. MusicFlow enables you to be creative and gives you the freedom to realize your vision. In contrast to traditionally custom-written music, you get your music in seconds or minutes rather than weeks. This allows you to save time and to experiment with ideas in a way that was not possible before.
Are you trying to replace human composers with computer algorithms?
Not at all! On the contrary, MusicFlow is all about connecting composers' music to listeners in a way that has never been done before. Each Dynamic Music Score is the artistic creation of the composer; MusicFlow enables composers to express their music in a way that allows it to be tailored to the individual needs of each listener. And whenever you buy a track, the composers get paid for their work. For composers, MusicFlow is a new way to earn money from their music and have a creative impact on the planet (see Composers section).
What's an Emotion Curve?
Each dynamic music score is characterized by a primary "emotion", "feel", or "mood" that the composer has chosen the music to convey. You tell MusicFlow how the emotion should flow as the music unfolds, by drawing an Emotion Curve that graphically illustrates the emotion varying over the length of the track. When you listen to the track you'll hear that the emotion curve doesn't simply make the music louder or softer -- it actually varies the structure and arrangment of the music to match.
Why should I use MusicFlow?
When you have made a video, film, slideshow or game you need music that fits perfectly with your visual contents and that conveys the right emotions in the right moments. This will make your production very engaging and give it more attention since "every movie is an emotional journey". And the price is very reasonable.

Using MusicFlow

How do I use MusicFlow?
You select one of our dynamic music scores (they all have different titles), select the length of the music you need (typically the length of your video/film/slideshow or the length of a scene) and then you draw the emotion of the music and click on the Preview button. Your personalised track is created and you can listen and decide if you are happy with the result. If not, you simply change the emotion curve, or the length or the music selection and try again. Once you are happy, just press "Buy Track", and once you've made the payment you will be able to download your track.
How do I draw the right emotion curve?
First select a dynamic music score of the genre you want, that has the right emotion for you. E.g. do you want something orchestral or jazz? Should the music convey excitement, joy or fear? We recommend that you watch your video/film/slideshow a few times to get a feel for the emotional intensity of the exprience, and perhaps take some notes as to the moments when the emotion is at a high or low or in betwen. Then you should be set to draw a curve that corresponds to your intuition. When the curve has a higher value more of an emotion will be conveyed, and when it is lower less of that emotion will be conveyed.
Here are some examples:
  • In this example below we use the "whale form" of the emotion curve and it means the music nicely gets builds up (in this case it builds of joy) and reaches an emotional crescendo around 45 seconds before it gently returns to the lowest emotion level.
  • In this example have created some gentle background music that stays at a rather low emotion level all the time. Even then, it has a proper beginning and end.
  • In this example the music is gentle but around 30 seconds it transits to its highest emotion level where it stays until the end.
  • In this final example we have used the "Silence" button to draw silence at the beginning and end of the track, so around 11 seconds the music will gently start from silence and just before 44 seconds it will nicely die out into silence. This creates a very professional result for creating music just for a scene in your video rather than non-stop music from the beginning to the end.
What does the Silence button do?
As we saw in final example above, when you click the Silence button you can "draw silence" and the music before the silence will finish in a gentle way that leads to silence whereas the music after silence will start in a subtle way from silence. Here are four typical cases:
  • Perhaps your video has a brief bit of dialog or sound event that you would like to hear without any music. You draw some silence in the that spot in the timeline. The music gracefully stops, the track is remains quiet for the duration you drew, and then the music resumes again.
  • You draw silence at the very beginning of the timeline, e.g. 0-15 seconds. The music will not have a definitive beginning as it normally does, but will instead gently begin from silence at 15 seconds. It will have a definitive end as usual though.
  • You draw silence at the very end of the time-line, e.g. 55-60 seconds if the total length is 60 seconds. The music will have a definitive beginning but just before 55 seconds it will gently move to silence.
  • You draw silence both at the beginning and end of the timeline. You then create an island of music which will have a gentle start and end and could be very appropriate for a scene in a longer video (see the final example above).
What's that voice saying "MusicFlow"? Why is it there?
That's an "audio watermark". We care about our composers, and we take seriously our responsibility to make sure they get paid for their creative work. Once you've bought the track, you will be able to download the track without any watermarks.
What is the maximum length of a track?
The maximum length is different for different dynamic music scores, but in most cases it is 8 minutes. If you need longer tracks--even hours of music--contact us at and we will cater to your needs.
How do I synchronize the track with my video/film/slideshow?
Open your video in some video player and identify the key time points when you want to convey an emotion or change in emotion. E.g. if you see that at 15 seconds there is a dramatic moment where the music should have a lot of excitement, then draw an emotion curve that peaks at 15 seconds.
To try out if the music fits with your video you can press play simultaneously on your video player program and play on MusicFlow that plays your track.
We are looking forward to integrating MusicFlow into video editors and other creation programmes and devices, to simplify and streamline the process fitting music to your contents.
