Alto and tenor clefs are movable C-clefs where the center indent points directly to Middle C (C4). In the alto clef, Middle C is on the middle (3rd) line; in the tenor clef, Middle C is on the 4th line up. By using Middle C as your anchor note, you can identify any pitch in under 5 seconds without counting through long semitone ladders.

Transposition means rewriting music so an instrument sounds at concert pitch, or rewriting concert pitch for a transposing instrument. For instruments in Bb (Clarinet, Trumpet), write the music a Major 2nd (tone) higher; for instruments in Eb (Alto Sax), write a Major 6th higher; for instruments in F (French Horn), write a Perfect 5th higher. Always calculate the new key signature first before moving individual noteheads.

A musical cadence is a two-chord phrase ending. You can identify any cadence in two easy steps: first, check the final chord (if it ends on Chord I, it is either Perfect [V–I] or Plagal [IV–I]; if it ends on Chord V, it is Imperfect; if it ends on Chord vi, it is Interrupted). Second, inspect the penultimate chord to lock in the exact progression.

In simple time signatures (2/4, 3/4, 4/4), each main beat divides into two equal parts (crotchet divides into two quavers). In compound time signatures (6/8, 9/8, 12/8), each main beat is a dotted note that divides into three equal parts (dotted crotchet divides into three quavers). The famous riddle: 3/4 has three crotchet beats per bar, while 6/8 has two dotted-crotchet beats per bar.

ABRSM music theory exams test Italian musical terms across four key categories: Tempo (speed), Dynamics (volume), Expression (mood), and Directions (navigation). Grouping terms by category and learning common Italian root prefixes (such as "-etto" meaning a little, and "-issimo" meaning very) lets you decode over 80% of required terms without rote memorisation.
