Orchestral seems to be the preferred word for classical music made with a computer and is sometimes also known as bgm music (background music). Classical is almost as old as music itself (well you know what i mean) and it also allows for a musician to sound like a whole symphony through ornate compositions. There are a surprising amount of brony musicians who specialize in this field of music and they are some of our most revered musical members of our community.
Check out these artists who specialize in this style of music.
Feel free to recommend some artists not included in here (these artists specialize in it) or include up to 10 of your favorite acoustic tracks in the comments section (for an eventual best of countdown).
