I make most of my musical work available under some form of Creative Commons license, so that others may get maximum enjoyment out of it. Note that not everything has the same license attached to it. If you're confused about what you are and aren't allowed to do with specific scores or recordings, questions may be directed to

Most of my scores are licensed under the Attribution-ShareAlike 4.0 International License. This basically means you can perform my compositions and arrangements, record them, and distribute the recordings, for profit or not, or even write new musical works based on my compositions, as long as (1) you give me full credit as the original composer/arranger, and (2) you distribute your own derivative works under the same terms.
The one exception so far is the score of the 1812 Overture transcription, which is licensed under the Attribution-NonCommercial 4.0 International License for complicated reasons I won't go into here.
Most of my solo video recordings are licensed under the Attribution-NonCommercial 4.0 International License. That means you're free to copy the video material (or just the audio) and use it in your own projects, as long as you credit me as the recording artist (and composer and/or arranger, where applicable), and you don't make money off of it. Notable exceptions to this rule are my recordings of Vladimir Horowitz's Carmen Fantasie, Sibelius' Finlandia, and John Williams' Imperial March from Star Wars. The copyright status of Horowitz's composition is not clear and to avoid conflicts I have left that video under the standard YouTube license. Finlandia is still under copyright in Finland (as well as the rest of the E.U.) but public domain in the U.S.A. and Canada. The Star Wars music is very definitely under copyright everywhere and I do not control the rights to it.
In contrast to the solo recordings, all my ensemble recordings are licensed under the Attribution-NonCommercial-NoDerivatives 4.0 International License. I make these more restrictive in case my collaborators are particular about how their work is used.
