Copy down the rhythm, and finish it by adding notes and rests to complete the last two measures. Be sure to continue with the accurate number of beats per measure, and use at least one rest and a variety of notes in each measure.

One possible

Bar 3: quarter note, quarter rest, two eight notes, quarter note

Bar 4: half note, half note

Explanation:

In the attachment, the yellow highlights, called bar lines, separate the bars.

There are four bars. Each bar has to have the same number of beats. I counted the beats in red. "+" means 1/2 a beat.

There are different types of notes, and they each have different amounts of beats.

See the first bar:

The first one with an empty head, a half note, is worth 2 beats.

The second one with a filled head, a quarter note, it worth 1 beat.

The third note is actually two notes together. They are two eighth notes, each worth 1/2 a beat. Together, they are 1 beat.

2 + 1 + 1/2 + 1/2 = 4

In the second bar, there are four quarter notes. Each quarter note is 1 beat.

Check the number of beats in this bar.

1 + 1 + 1 + 1 = 4

For the third and fourth bars, choose any combination of notes that give you 4 beats.

See the other picture for a summary of notes and rests.

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !

i think it's but if you get it wrong its not my fault : )
