The Rubric Bank

Maintaining a consistent and continuous tempo throughout the performance

Accuracy in playing notes and avoiding deviation from correct pitches

Controlling and varying volume level in a deliberate manner

Conveying a feeling or meaning to the listener through musical performance

Accuracy of note timing and sequence within the rhythmic framework

Sound cleanliness from noise and interruption, and recording technical quality

Adhering to chosen musical scale or modulating to it intentionally

Controlling sound quality and color to serve musical expression

Constructing performance with cohesive structure: intro, development, climax, outro

Ability to create music spontaneously within a musical framework

Musician's ability to choose the right complexity level for each context

Musician's complete presence in the moment during performance

Musical taste in making decisions that beautify performance

Musician's ability to create genuine dialogue with their listeners

Mastering advanced instrument or voice techniques and using them expressively

Hitting the Arabic neutral note (quarter-tone) precisely in cents, not rounding it to the nearest Western semitone.

Executing the Arabic rhythmic cycle's structure (dum/tak) at its correct time positions (Maqsūm, Maṣmūdī…).

Identifying the maqām from playing or singing (Rāst, Bayātī, Ḥijāz…) and separating those sharing a root jins.

Building the maqām's sayr: opening from the root, expanding toward the octave, and closing on the tonic.

Using vocal/instrumental ornaments (vibrato, glides between quarter-tones, repeats) at climax and tonic points.

Building a coherent improvised maqām taqsīm that develops the sayr, builds tension to the octave, and closes convincingly.

A deliberate departure from strict tempo — calculated slowing or quickening — used for expressive effect, without the performance losing its underlying pulse or its cohesion between voices or instruments.

Using graded shifts in loudness to build an emotional arc within a single melodic phrase, rather than performing at one unvarying volume.

Using suspensions or chromatic passing tones to create harmonic tension and then resolve it in service of musical drama — not merely a theoretically correct chord sequence.

Placing accents outside the beat's expected positions with clear timing precision — a deliberate rhythmic choice, not a timing mistake.

Changing the quality of the sound itself — its warmth, edge, or roughness — through control of bow pressure, breath support, or vocal placement, in service of expressive meaning rather than as an incidental byproduct.

Shaping the performance as a single dramatic arc spanning the piece from start to finish — gradual build, a clear climax, then release — rather than playing each section in isolation from what precedes and follows it.
