Indonesian rock is the broad umbrella for guitar-driven popular music from Indonesia, blending Western classic, hard, and progressive rock with local sensibilities, Bahasa Indonesia lyrics, and occasional traditional melodic or rhythmic inflections. Its core sound ranges from riff‑based hard rock and bluesy classic rock to 1990s alternative and grunge aesthetics. Many acts favor memorable, sing‑along choruses, melodic guitar leads, and groove‑forward rhythm sections. Some landmark experiments weave gamelan‑like ostinati, pentatonic figures, or modal flavors into modern rock arrangements, giving the scene a distinctly Indonesian character.

Sholawat is an Indonesian Islamic devotional song tradition centered on lyrical praises and blessings upon the Prophet Muhammad (salawat). It bridges Arabic liturgical poetry with local musical aesthetics, most commonly voiced in Arabic and Indonesian. Traditionally performed in pesantren (Islamic boarding schools), mosques, and community gatherings such as maulid and haul commemorations, sholawat relies on call-and-response vocals and frame-drum ensembles (rebana/terbangan, hadrah, marawis). In contemporary practice, it also appears in pop-influenced formats with keyboards, oud (gambus), violin, bass, and light percussion, making it accessible to younger audiences while retaining its devotional core. Melodically, sholawat often draws on maqam (modal) flavors such as Hijaz, Bayati, and Nahawand, with ornamental, melismatic singing. Its rhythmic palette spans simple 2/4 and 4/4 grooves to Middle Eastern-derived patterns (e.g., malfuf and wahda), adapted to Indonesian ensemble practices.
