Metric Modulation Calculator
Use the Metric Modulation Calculator to compute tempo adjustments based on metric modulation principles. For a quick calculation, select Basic Calc and enter values for Old Tempo (bpm), Number of Pivot Note Values in the New Measure, and Number of Pivot Note Values in the Old Measure. Leave Metric Modulation (New Tempo) empty to calculate it automatically.
For a detailed calculation, choose Advanced Calc, where you input values for Old Tempo (bpm), New Note Value, and Old Note Value. The Advanced Metric Modulation (New Tempo) will display the adjusted tempo automatically upon calculation. Click Calculate to get the results or Reset to clear all fields.
Input Field Purpose
| Input Field | Purpose |
|---|---|
| Old Tempo (bpm) | Enter the initial beats per minute for the piece. |
| Number of Pivot Note Values in the New Measure | Specify the number of pivot note values in the new measure for modulation. |
| Number of Pivot Note Values in the Old Measure | Specify the number of pivot note values in the original measure for modulation. |
| Metric Modulation (New Tempo) | This field displays the calculated tempo after modulation. Leave it empty for automatic calculation. |
| New Note Value | Enter the relative note value (e.g., Quarter = 1, Eighth = 0.5) for the new tempo. |
| Old Note Value | Enter the relative note value for the original tempo. |
| Advanced Metric Modulation (New Tempo) | Displays the new tempo after advanced calculation, based on modulation settings. |
How To Calculate
Example 1 – Basic Calculation
| Step | Calculation Process |
|---|---|
| Step 1 | Enter Old Tempo (bpm) as 120. |
| Step 2 | Enter Number of Pivot Note Values in the New Measure as 4. |
| Step 3 | Enter Number of Pivot Note Values in the Old Measure as 3. |
| Step 4 | Leave Metric Modulation (New Tempo) blank. |
| Result | The calculator displays the New Tempo as a result of modulation. |
Example 2 – Advanced Calculation
| Step | Calculation Process |
|---|---|
| Step 1 | Enter Old Tempo (bpm) as 100. |
| Step 2 | Enter New Note Value as 0.5 (e.g., Eighth note). |
| Step 3 | Enter Old Note Value as 1 (e.g., Quarter note). |
| Step 4 | Click Calculate to view the Advanced Metric Modulation (New Tempo). |
| Result | The calculator displays the adjusted New Tempo in bpm based on the advanced settings. |
