Create a soothing and tranquil meditation track in the genre of ambient electronic music. Set the key to D major to evoke a sense of calmness and serenity. Infuse the composition with gentle and flowing synth pads, layered with ethereal soundscapes and minimalistic percussion. Maintain a slow tempo and incorporate a steady, rhythmic pulse to guide the listener's meditation practice. Immerse the track in a peaceful and introspective mood, allowing for relaxation and deep focus.
