Imagine the room dimmed, a mat under you, and the first sound you hear is a hand drum rather than a voice giving instructions. That is the opening the video's description promises: an invocation played live, followed by Spanish and acoustic guitar moving the class through a slow, floor-based practice, and finally a gong bath during savasana. Dennis Lang's full moon class, filmed with Kathy, is built on a simple premise. The full moon is considered a very yang time of the month, so the teachers counterbalance it with yin yoga, a practice of long, quiet holds that asks the body to rest rather than push. The result is less a workout than an hour and a half of deliberate slowness, with music doing much of the work of setting the tone.
The structure follows a pattern familiar to anyone who has taken a yin class. Students settle into shapes and stay in them for an extended period, typically several minutes at a time, letting gravity and time do the stretching instead of muscular effort. The description for this session states that no prior experience is required, which suits yin well, since its postures are generally about placement and patience rather than strength or balance.
What distinguishes this particular class is the way it is sequenced around sound. The music is not background texture added to a recording; it is presented as part of the live practice, opening with the drum invocation and moving through guitar. For a student, that means the audio becomes a set of landmarks. You know the invocation marks the beginning, the guitar carries you through the middle hours of holding, and the gong marks the place where effort is meant to dissolve completely.
The logic here rests on the yin and yang vocabulary that runs through many traditional East Asian and yogic frameworks. Yang is associated with activity, heat, outward motion, and expansion. Yin is associated with stillness, cooling, inward attention, and receptivity. The video's description characterizes the full moon as a yang moment, which is why it recommends a yin practice to balance it. Whatever one makes of the cosmology, the practical effect is easy to feel: a bright, energetic night tends to pull attention outward, and a yin session asks the opposite question of where you are holding tension.
It helps to understand what yin yoga is doing physically, because that is the part of the framework that can be checked on the mat. Yin postures are typically held longer than the muscular, dynamic movements of a vinyasa class. The usual explanation is that long, passive holds load the deeper connective tissues, such as fascia and ligaments, rather than the muscles that move the body. Practitioners often describe the sensation not as a stretch that must be forced but as a slow settling into the edge of comfort, which is why the instruction to use props and honor the body carries so much weight in this style.
Most yin classes lean on a teacher's voice and a quiet room. Adding live instruments changes the acoustic environment in a few specific ways. A hand drum at the start gives the room a rhythmic pulse that is easy to settle into, and it signals that the practice has begun without a lecture. Acoustic guitar tends to be warmer and closer than amplified sound, which suits the intimate, inward quality of a yin hold. Spanish guitar adds a different phrasing and a more melodic, flowing texture, and the contrast between the two guitar voices gives the long practice variety without asking the body to change its work.
There is also a practical benefit. When the music is performed live, the rhythm is responsive to the room rather than locked to a timeline. For students who have sat through many recorded sessions, a live instrument can feel like a human presence guiding the hold, which is part of why these sessions reward attention rather than distraction.
Savasana, usually translated as corpse pose, is the final resting posture in most yoga sequences, performed lying on the back with the body released and the breath left to find its own rhythm. In this class, the description specifies that the closing savasana is a gong bath. A gong bath means the sound of the gong is allowed to wash over the room as students lie still, with no movement required and nothing to correct.
Ending with sound in savasana makes a particular kind of sense for a yin practice. The class has spent its length asking the body to stay and receive. The gong gives the nervous system something to attend to at the moment when the mind might otherwise drift toward the to-do list. Many practitioners find that the sound's long decay gives the attention a place to rest, which is a natural extension of a practice built around stillness.
The description notes that during the practice, Kathy will share the history of the full moon based upon Indian mythology. That is a meaningful part of the session, because it places the lunar cycle inside a story rather than only a calendar. Students who come for the physical practice may find the narrative a second layer of meaning, giving the full moon a cultural and mythic context while they hold their shapes.
This article does not reproduce that mythology, because the source material available for this piece consists of the video's title and description rather than a transcript of what is said. Anyone who wants the specific stories should watch the session directly, where the teacher's own telling is the authoritative version.
The description offers two pieces of guidance that matter more than any single posture. First, it invites students to use any props that make them comfortable in the shapes. Bolsters, blankets, blocks, and straps are common tools in yin practice, and they allow the body to stay in a pose for minutes without strain. Second, it asks students to honor their body. In a yin context, that phrase is not decorative. Because the holds are long, the difference between a productive edge and an unhelpful strain is subtle, and the sensible rule is to back off whenever the sensation turns sharp or unpleasant.
Because no prior experience is required, a first-time student can treat the session as an introduction to slowness itself. It is reasonable to expect some restlessness early on, especially in the first holds. That restlessness is part of what the practice is designed to reveal, and it usually softens as the music carries the room.
The description is clear that the practice can be done at any time but is especially useful during a full moon. That framing is worth taking seriously as an invitation rather than a rule. A yin session is useful whenever a person has spent a stretch of days running on high energy and needs a counterweight. The full moon simply provides a calendar marker for doing so, a reason to pause on a particular night and let the body and the sound do their slow work.
If this class appeals to you, the most useful next step is to watch the full session with a few props close at hand and a willingness to stay in each shape longer than feels comfortable at first. Pay attention to the drum that opens the practice, the guitar that carries the middle, and the gong that closes it, and notice how the sequence changes the quality of your attention.

Start with one full moon, one unhurried hour, and the simple instruction the teachers return to: honor your body.
