Drum rhythm patterns using quarter and eighth notes in 4/4 time signature.

This sheet music is a rhythm exercise designed to help you practice reading and playing combinations of quarter notes (1/4s) and eighth notes (1/8ths) in 4/4 time.

Here is how to read it:
* The Time Signature (4/4): This means there are 4 beats in every measure (the space between the vertical lines). You need to count "1, 2, 3, 4" for each measure.
* Quarter Notes (♩): These look like a black note head with a stem. They get 1 beat. You clap or tap once on the beat number (e.g., on "1").
* Eighth Notes (): These look like two note heads connected by a beam. Two eighth notes together equal 1 beat. You split the beat in half. Instead of just saying "1", you say "1-and". The first note is on the number, and the second note is on the "and".

How to practice this sheet:
1. Set a steady tempo (speed) where you can comfortably count out loud.
2. Start with the first line. Count "1, 2, 3, 4" while tapping your foot on the numbers.
3. Clap the notes exactly when they happen:
* If it's a quarter note, clap on the number.
* If it's a pair of eighth notes, clap on the number AND the "and".
4. Move to the next line only when you can play the current line perfectly without stopping.

Since this is a performance exercise rather than a question with a single numeric answer, the "solution" is successfully performing the rhythms as written.

Final Answer:
The task is a rhythm training exercise. To solve it, you must clap or tap the notes in 4/4 time, counting "1, 2, 3, 4" for each measure. Play quarter notes (♩) on the beat numbers and eighth notes (♫) on the "and" counts between the beats (e.g., "1-and, 2-and").
