Groove Machine: worksheet
Write about the activity only. Leave out names, class periods, emails, and other personal details.
Predict the signed drift at the START of measure 4 before each try. Use quarter-note beats: positive means late, negative means early. Watch the beat display and drift graph; sound is optional.
MU:Cr2.1.C.HSI
Level 1: Rock beat in 4/4
| Predicted drift at start of measure 4 (quarter beats) | Measured drift (quarter beats) | Totals in measures 1-4 | Passed? |
|---|---|---|---|
1. Write one measure of your pattern, including note/rest values and drum sounds. Did all four measures lock in? MU:Cr2.1.C.HSI
2. Explain why each measure must have the right total, even if all four measures add up to the correct grand total. MU:Cr2.1.C.HSI
Level 2: Waltz in 3/4
| Predicted drift at start of measure 4 (quarter beats) | Measured drift (quarter beats) | Totals in measures 1-4 | Passed? |
|---|---|---|---|
3. Write one measure of your pattern, including note/rest values and drum sounds. Did all four measures lock in? MU:Cr2.1.C.HSI
4. A four-quarter-note pattern is reused in 3/4. Predict the drift at the start of measure 4 and explain your calculation. MU:Cr2.1.C.HSI
Level 3: Jig in 6/8
| Predicted drift at start of measure 4 (quarter beats) | Measured drift (quarter beats) | Totals in measures 1-4 | Passed? |
|---|---|---|---|
5. Write one measure of your pattern, including note/rest values and drum sounds. Did all four measures lock in? MU:Cr2.1.C.HSI
6. Both 3/4 and 6/8 contain six eighth notes. How do their groupings and strong beats differ? MU:Cr2.1.C.HSI
When a performance missed
7. Pick one performance that missed. Which level was it, and what went wrong? Use the rule the game showed you. MU:Cr2.1.C.HSI
