I think that is true for the Pratyeka (solitude); which is a practice for those in between Buddha Sasanas, or where there is no Dharma Dispensation. Also, solitude in a tranquil place is recommended jhana meditation; which is big part of practice for Shravakas. However, the three refuges are not the Buddha, the Dharma, and Solitude. In addition, the teachings were originally not put into writing' -- they were spoken and heard. Also, there is no need to cultivate the Brahma Vihara or Kshanti if one's practice is solitary.
Moreover, the path / vehicle of Bodhisatta / Bodhisattva;' which is generally stressed in Mahayana, definitely involves interaction with others. Jan Nattier has suggested that Mahayana was originally a synonym for the Bodhisattvayana. On topic, I think there is reason why devotional practices and rituals so often involve music and singing. Also, why Mantras and Devotional Chanting are such a big part of most actual, traditional, real world branches of Buddhism.
Sound conveys emotion and feeling in a powerful way. It can make us feel stressed, blissful or calm. Also depressed or joyous, sensuous or spiritual, bored or energetic, hostile or kind, restless or patient, cruel or compassionate, and so on. I have noticed a similarity between the tone of the Great Compassion Mantra and
good Blues Music. Both are lamentations of sorts, but there is profound empathy and also a sense of victory over emotional pain and suffering -- the courage to honestly face the pain and still overcome. The shared joy of victory over suffering and evil is further celebrated in joyful devotional hymns, such as Jaya Mangala Gatha.
Sound is especially important in Nichiren Buddhism. The primary practice IS devotional chanting. Ritual is like the main course, not a mere side dish or extraneous desert,
