This will come into effect from January 2018, so if you are studying for a grade right now i wouldn't worry to much.
Lets have a look at what they have to say.
This was taken direct from the Trinity Rock & pop website
Rock & Pop 2018 is coming soon
Real songs. Real skills. Real progress.
With exams starting January 1 2018, the new Rock & Pop 2018 syllabus will be launching in September.
Real songs: Play the music you love with our huge range of songs spanning all contemporary styles. Choose your set list from the eight songs in our new graded books, play a song of your own choice, or perform a song you’ve written yourself.
Real skills: Develop the improvisation and playback session skills that professional musicians need. Prove your technical skills in a real-life context through our technical focus songs and demonstrate your ability to deliver a compelling live performance.
Real progress: Achieve your goals with an externally regulated and internationally recognised qualification. Trust the 140-year heritage Trinity brings to contemporary music, and benefit from being marked by industry experts.
The Rock & Pop 2018 syllabus comes complete with brand new song lists featuring a huge range of well-known rock and pop music from David Bowie to Daft Punk, from Adele to AC/DC, and from The Beatles to The Black Keys, and is accompanied by new songbooks featuring eight songs with background information, performance tips and professionally recorded backing and demo tracks. Further support comes in the form of a wide range of online material, to give teachers and learners the full Rock & Pop experience.
Lets see if this is just much of the same as before. Hopefully better songs in the lower grades.
