Bar lines | A vertical line that appears before each strong beat. Divide the stave into equal measures. |

Beat | Unit of time, usually measured in crotchets. |
Semibreve | A note lasting 4 crotchet beats. |

Time signature | Two numbers placed one on top of the other. Top number = how many in a bar. BOTTOM number how LONG each beat is. |
Strong beat | The first beat of each bar. |
Simple time | You count ALL the beats. The beat is easily divided into 2's or 4's. The time signature TOP number is mostly 2, 3, or 4 |
Compound time | You count the BIG beat - The beat is divided into 3's. The time signature TOP number has 6, 9, or 12. |
Anacrusis | An up beat before the first complete bar of music. A phrase that starts on a beat before a barline. |
Triplet | A SIMPLE TIME beat that has been divided into 3 INSTEAD OF 2 or 4 |
Augmentation | A device that takes a melody then doubles the value of each note in the phrase. |
Diminution | A device that takes a melody then halves the value of each note in the phrase. |
Cross rhythms | Two different patterns of that are played together to create a more complex pattern. |
Syncopation | Chords or melody notes that are not played ON the beat but appear in the 'gaps' between. |
Tempo | The speed of the music. |
BPM | Short for Beats Per Minute. 60bpm = 1 beat per second |

Metre - Regular | The pattern of beats. 2 beats per bar=duple metre. 3 beats = triple metre. 4 beats = quadruple metre. |
Metre - Irregular | The pattern of beats. In a 5 beat bar they could be grouped in a 3+2, in a 7 beat bar grouped 4+3 etc. |
Dotted notes | A dot after a note makes it last 1/2 as long again. i.e a 2 beat note (minim) with a dot 2+ (1/2 again) 1 = 3. |
