First of all, absolutely love the initiative! This thread has put in words a lot of what I've experienced in music in general. So indeed, some praise for this undertaking is in order before delving deeper into it. I recognize the arguments made by @
TheTranceHistorian. The point of others here that this specific view is highly personal and therefore only works in a way to reinforce the experience of a selected group, whereas it can be uninviting for others, should also be considered. But I think there is a nice middle ground here in terms of application.
The fact that the effects Trance music can have as detailed by several users in this thread are valid is undeniable, as they form the core experience of someone's perception. As someone who spent quite some time on other social media platforms where Trance is present, it seems like there is a large group of people, especially ones who mainly visit live events, who appreciate Trance at its surface level only; as a "boom boom" music. I think that is valid as is. However, it forms a social stigma that I am also confronted with very often. Bringing across the depth of the layers underneath can be challenging, especially to people who have not experienced something like it before. Often do I encounter people who are not capable of recognizing that emotion in music can be more complex than "happy" or "sad". They claim Trance is always happy because it is energetic. How do you bring across your experience in an inviting way, without sounding arrogant or elitist?
By explaining the
personal emotional impact. A body of work like this can help people express their feelings in words, which in turn can help them communicate their enthusiasm to others. I understand that a passion for something niche can be quite lonely. I have been there. A work like this could considerably help. Not necessarily to make others enthusiastic for Trance music, but perhaps in order to plant a seed, and slowly erode the stigma. Or in order to let them understand the source of the passion.
As an example, I know plenty of people who were passionate about Trance for a while for the reasons mentioned earlier, but grew out of it eventually. Why? The specific emotional themes were no longer an addition to their lives. Some ended up listening to Rock music, some to other genres. Music has value because it elevates us to a certain state, the flow or place where we want to be. This goes for spiritual, relaxing, party music regardless. But for this to have effect the music has to contrast with our current lives. For instance, Ambient might have a more significant impact on people who want to relax than on people who are already relaxed.
So what does this say about Trance music? The spiritual part is a reflection of the psychic state of the listeners. I personally listen to emotional Trance because it can contrast with my emotional state at any time. Because it is a complex mix of evolving contrasts, it tells a story which can hit many aspects of my life. Therefore it brings balance by opening my mind, therefore inducing a flow state. I release all negative emotions. I think incorporating these personal analogies can deepen the sense of the book, by introducing a more human connection. Especially when considered in the light of what others look for, and find, in other genres, as mentioned before.
Anyway that's just my input here, hope some sense can be found in it
Although it’s better when my wife does!
