Kirtan is an ancient practice of connecting with the divine through the "call and response chanting" of ancient mantras - often praising specific deities like Lord Shiva, Lord Krishna, Goddess Durga/Kali, etc - generally with musical accompaniment. 

The word "mantra" literally means "delivering/protecting the mind".

Kirtan often begins with a contemplative/meditative and mellow musical introduction and, with the leader setting the melody and mood and the assembly responding, typically builds in intensity until those present feel the urge to dance.

Kirtan is a spiritual practice derived from Hindu traditions (Bhakti Yoga) and is also important in Sikhism and some forms of Buddhism, but it is not a "religion" in itself. It is often practiced in secular settings like yoga studios.

The purpose is to connect with the divine (whatever that means to you), calm the mind, and experience inner peace and joy through the power of sacred sound.

Sessions usually involve the repetition of mantras or devotional songs (bhajans) in a call-and-response format, often accompanied by instruments like harmonium, tabla, and kartals (small cymbals). The pace and volume may build to a crescendo and then soften again.

Chants often use Sanskrit or other sacred languages, but transliterated lyrics are usually provided. The leader typically chants a line, and the group repeats it (call-and-response), making it easy to follow along.

No, you do not. Kirtan is a practice for everyone, regardless of musical ability. The focus is on opening your heart and participating, not on performance.

Mantra is a sacred sound, word, or phrase repeated to aid in concentration and spiritual transformation. Popular examples include the Hare Krishna mantra or "Om Shanti Om".

The word "mantra" literally means "delivering/protecting the mind".

Our minds in our everyday lives are typically absorbed in the ups and downs of life - sometimes happy, sometimes sad, sometimes scared, etc.  And we might be burdened by unhelpful thoughts or worldviews.

Because of the divine origins of these mantras, they have the power to elevate our consciousness - to rise above the pains and mundane pleasures, the fears and anxieties, the craving and the lamenting and to situate us on a higher plane of consciousness whereby we no longer identify wholly with the temporary fortunes and misfortunes of this world, realise our eternal natures distinct from the bodies we inhabit and feel genuine love, compassion and kinship for all sentient beings.

Kirtan offers a transcendent form of pleasure - ananda/bliss - far beyond any gratification otherwise available in this mortal realm.

One certainly doesn't need to approach it that way - and there is no pre-requisite of conforming to particular beliefs in order to participate.  The key thing is to listen and respond.  That said, the most potent essence of any mantra is the name of the deity being praised or petitioned - and if there is genuine affection and regard for them in one's chanting, then They reciprocate and confer their blessings.  The process is experiential - with no conditions imposed on the participant.

No. Kirtan is for all people and focuses on universal spiritual principles like love and devotion, not religious affiliation.

Experiences vary, but many people report feeling relaxed, joyful, blissful, and connected to others or a higher power.

Yes, the practice of chanting is known for its ability to reduce stress, promote emotional well-being, and quiet the "monkey mind".
