My Melody Calculator helps you quickly and easily perform basic arithmetic calculations.

## How to Use the Calculator

- Enter the first number in the “Number 1” field.
- Enter the second number in the “Number 2” field.
- Select the mathematical operation you want to perform from the “Operation” dropdown.
- Click on the “Calculate” button to compute the result.
- The result will be displayed in the “Result” field.

## How It Calculates the Result

The calculator performs basic arithmetic operations based on your selection:

**Add:**Adds the first number to the second number.**Subtract:**Subtracts the second number from the first number.**Multiply:**Multiplies the first number with the second number.**Divide:**Divides the first number by the second number. If the second number is zero, it will output an error message.

## Limitations

The calculator is designed for basic arithmetic operations and handles simple calculations involving two numerical inputs. It does not support:

- Complex mathematical functions like exponentiation, roots, or trigonometry.
- Handling of non-numeric inputs or very large/small values beyond standard floating-point precision.
- Operations on more than two numbers at a time.
- Advanced error handling beyond division-by-zero.

## Use Cases for This Calculator

### Use Case 1: Calculate BPM (Beats Per Minute)

Enter the total duration of your melody in minutes and the number of beats in that duration. Hit calculate to get the BPM of your melody. Use this to ensure your music matches the desired tempo perfectly.

### Use Case 2: Determine Time Signature

Input the number of beats in a measure and the note value representing a single beat. The calculator will display the time signature of your melody, helping you understand its rhythm and structure.

### Use Case 3: Convert BPM to Timestretch Factor

Provide the BPM of your melody and click convert to find the corresponding timestretch factor. This feature is handy for adjusting the tempo while maintaining the original pitch of your audio recordings.

### Use Case 4: Calculate Melody Length

Select the BPM and total number of beats in your melody to determine its length in minutes. This calculation assists in planning the duration of your music compositions accurately.

### Use Case 5: Determine Delay Time in Milliseconds

Enter the BPM and desired delay length in beats to compute the delay time in milliseconds. Perfect for musicians and producers looking to achieve specific rhythmic effects in their compositions.

### Use Case 6: Time Alignment for Audio Tracks

Input the BPM and desired time shift in beats for multiple audio tracks. The calculator will show the precise time adjustment needed for synchronization, ensuring seamless blending of different elements in your music production.

### Use Case 7: Calculate Swing Time Percentage

Specify the desired Swing Time percentage and tempo to determine the exact timing shift for creating swing rhythms in your melody. This feature adds groove and dynamics to your music arrangements.

### Use Case 8: Calculate Delay Feedback Time

Enter the BPM, delay time, and feedback percentage to calculate the duration of delay feedback in your audio effects. This functionality aids in achieving depth and ambiance in your soundscapes.

### Use Case 9: Determine Tempo Change Percentage

Provide the original BPM and the new BPM to calculate the percentage change in tempo. This tool is ideal for adjusting the speed of your music production smoothly and accurately.

### Use Case 10: Calculate Pitch Shift for Melody

Specify the original BPM, new BPM, and the current pitch to calculate the required pitch shift percentage. Use this feature to transpose your melodies effectively while maintaining musical integrity.
