Familiarize yourself with the trance genre. Research other DJs and producers such as Paul Oakenfold, Armin Van Buuren, and Seb Fontaine. Listen to their mixes, mix CDs, or shows and pay attention to their transitions and programming.
Acquire trance music from record pools, record stores, or on line. Ask other DJs to trade music with you or subscribe to a music service that will send you trance tracks.
Listen to some of your favorite trance songs and practice mixing with them. Assuming you already have some idea of how to mix, try blending or mixing the tracks that you have that sound similar in production, making sure your beats or BPMs (beats per minute) match. Programming is key to being a good DJ. When you choose the right songs that blend and sound well as you mix them together, it's almost like"'telling a story" as you mix.
Practice as much as you can to fine tune your technique and transitions. Record yourself and listen to your mixes to see where you think you could improve as a DJ.
Promote yourself online on social networking sites, rave sites, and other music or trance forums. Sites like The DJ List are great for DJs trying to get noticed. Promotion is key when it comes to landing DJ gigs, especially as a trance DJ. Trance is not a mass appeal genre that you will hear at most clubs. It's definitely not a genre requested at weddings or most mobile gigs. But they're great gigs for getting promotion as a DJ, in general.
Attend shows or raves where trance DJs are performing. Get a vibe of how other trance DJs perform and even pick up some tips or hear tracks that you haven't heard.
Network with the DJs on the roster or even the promoters involved. The promoters are the ones that book the talent for the big parties, shows, and raves. Have a few demos on hand in case they ask or bring some business cards with your email and a website with links to your mixes, if available.
