This description outlines the creation of a supportive, deep bass line for a piano-driven piece, intended to convey a "half-time ballad feel." The core of the sound is a prominent piano melody or chords, underpinned by a deep, sustained bass (preferably a "Sub Bass" or "Sine Bass" for chest-rattling depth, or an "Arco Double Bass" / "Cellos" for an orchestral feel). The tempo is explicitly set at 120 BPM, but the instruction to play "slowly" for the half-time feel implies a perceived tempo of 60 BPM for the harmonic rhythm. The bass notes are whole notes, perfectly filling each bar, indicating a 4/4 time signature. The bass line is simple, following the root note of the piano chords, maintaining consistent velocity, and synchronizing with the kick drum on beat 1 to act as a "steady anchor" and "glued low end." The overall style leans towards a melancholic or introspective ballad, possibly cinematic, with a focus on depth, sustain, and a non-distracting, foundational low end.
