Hybrid Orchestral Composition and Sound | Trailer Music Course
Start creating a larger-than-life sound with Randon Purcell's trailer music course, "Hybrid Orchestral Composition and Sound."
Hybrid orchestral music was and still is one of the most demanded styles by today's music publishers. From production music, to film and trailer music, there is no way around it. Epic orchestral compositions paired with earth shattering sound fx and synths - it's simply one of these styles every composer should know about.
Master The Score teamed up with non other than Brand X in-house composer Randon Purcell wo already helped hundreds of students in crafting their trailer music skills. In this massive trailer music course Randon walks you through everything you need to know to produce the next hybrid orchestral trailer hit. His composition and production skills earned him placements like Kong vs Godzilla, World of Warcraft, Call of Duty and many more.
To give our students the best possible learning experience we made sure to include music that was actually used in big campaigns. Besides hours of fundamental training and live composing, Randon walks you though his track "Chaos Theory" which was used in the campaign for "World of Warcraft".
Randon Purcell
Randon’s childhood was filled with music, learning classical piano from his mother from the time he was 5.
Since 2014 Randon has focused almost entirely on instrumental compositions for both trailer and production music. He has released dozens of industry albums with various publishers around the world and now works exclusively for Brand X Music in Los Angeles, CA.
Randon has had hundreds of production music placements on several networks, including HBO, ABC, NBC, CBS, Discovery, Sundance Channel, Travel Channel and History Channel. Some of his most recent trailer placements (music and sound design) include: Godzilla vs. Kong, Separation, Call of Duty Modern Warfare, World of Warcraft, Jurassic Hunt, Legacy of Lies and Red Shoes and the Seven Dwarfs.
In 2019 Randon started a sound design & virtual instrument company, Fallout Music Group, with his friends Andrew Skipper, Kyle Kniceley, and Simon Haglund. They build custom instruments and tools for media composers.

I have purchased almost every trailer course available and by far the Hybrid Orchestral Composition and Sound course is the best! BY FAR!! Looking forward to future courses and will only purchase Master the Score courses in the future. You have cutting edge content and the material is over the top in quality. Thank you for contributing to the education of us hoping to get into the world of music composition as a profession!

The Hybrid Orchestral Roadmap
The course is divided into 6 sections:
This course is divided by the following steps:
Let's talk about the basics
The first section focuses on some of the fundamentals of hybrid orchestral trailers. Randon discusses the different acts of a trailer, the general structure and length for each of the acts, and some best practices to help make your music easier for a trailer editor to use. Finally he explores some helpful tips and ideas for each of the 4 acts.
This section will make sure you have a strong fundamental understanding of all the concepts Randon is going to build upon. After this section you are well prepared for the more advanced concepts in later sections.

- fundamentals of hybrid orchestral trailers
- structre
- best practices
- tips on each act
Favourite instruments and libraries
Randon is often asked what libraries and instruments he likes to use for hybrid orchestral music. With so many options out there on the market, it can be overwhelming and difficult to choose. In this section, Randon will discuss a number of his favorite instruments for this style of writing, complete with some examples of how they sound and how he likes to use them. Randon explores percussion libraries, brass libraries, string libraries, synths, trailer FX and some favorite audio processors. He teaches his students how to achieve a huge and impactful sound by layering different instruments and effects.
This section will equip you with everything necessary to create largen than life tracks.

- layering techniques
- essential sound combinations
- favourite sample libraries
- favourite plugins
- favourite synths
Fundamentals
After building the strong fundamentals in the previous lessons, section 3 is where the fun really begins.
Randon jumps right into action by guiding you through different composing workshops. He dives deep into writing for the various instrument and fx groups such as strings, brass, percussion, synths and more.
By following Randon as he composes live and unscripted, you will gain a deep understanding on how to write for the different orchestral sections.
Randon made sure to include all the midi files for his students to study, to provide even deeper insights on how he approaches orchestral writing.
To finish of this section Randon explores the writing of Ostinati. As Ostinati are so common and such a powerful tool, this workshop will make sure you are well equipped with techniques on how to write them.

- how to write for strings
- how to write for brass
- how to write for percussion
- how to write for synths
- how to write ostinati
Compositional Building Blocks
In this section students will put everything into practice. Randon creates many different chord progressions and starts to build on them by adding percussion, brass, strings, synths and fx.
The goal of this section is to make students familiar with a simple workflow that transforms every chord progression into larger than life wall of sounds in no time.
By following Randon and completing the assignments, students will take advantage of a highly practical learning experience.

- create heroic chord progressions
- create menacing chord progressions
- write ostinati
- write for percussion
- write brass and string arrangements
- add synths and fx
Ground Up Composition
Building on all previous sections and especially the individual workshops, Randon dedicates section 4 on composing a complete hybrid orchestral track from beginning to end.
Students follow Randon in realtime, composing his next trailer hit, while absorbing every detail of the production process. This makes sure they will gain a deep understanding of a proper workflow and all the compositional aspects of producing hybrid orchestral music.
Randon starts out by sketching the piece and explaining his thought process. Based on this sketch Randon then starts producing the different acts of his piece. To finish up this wonderful section Randon mixies his complete track so that it can be presented to major publishers.

- structuring a track
- sketching out a track
- creating act 1-4
- layering instruments
- using fx
- mixing the complete track
Deep Dive: "Black Mirror"and "Chaos Theory"
In section 5, Randon dives into his track, “Chaos Theory”, published by Exodus Music. This track has been used in World of Warcraft advertising campaigns and is definitely more of a standard trailer format for an action-based hybrid orchestral piece.
Randon starts with an overall analysis of the track and follows up with an exploration of each of the acts, breaking them down into each of the instrument groups and showing examples of layering and composition for each group.
Randon then walks you through a second track called “Black Mirror”, published by InfraSound Trailer Music. This track would fall into the "slow burn" side of hybrid orchestral music, which can be very different from your typical action hybrid orchestral trailer.
In a last bonus deep dive video, Randon analyzes the music used for the course introduction itself. Strings, brass, percussion, FX all explored in detail.

- how to focus on ideas
- how to make your tracks licenseable
- how to write for the different sections
- how to structure a track
