Getting Started: The Basics

Blob Opera is an interactive music experiment that lets you create opera harmonies using four AI-powered singing blobs. Each blob represents a different vocal range, and together they can create beautiful four-part harmonies.

Step-by-Step Tutorial

1 Understanding the Four Blobs

Each blob represents a different vocal range in a traditional opera quartet:

Soprano (Red): The highest voice, bright and soaring
Alto (Yellow): Lower female voice, warm and rich
Tenor (Blue): Higher male voice, powerful and expressive
Bass (Green): Lowest voice, deep and resonant

2 Selecting and Controlling Blobs

Click or tap any blob to select it. Once selected, you can control two key parameters:

Pitch (Up/Down): Drag up to make the note higher, drag down for lower notes
Vowel Shape (Left/Right): Move horizontally to change the vowel sound from "ah" to "oh" to "ee"

3 Creating Your First Harmony

Start with a simple chord:

Select the bass (green blob) and position it at a low, comfortable pitch
Add the tenor (blue blob) at a slightly higher pitch
Place the alto (yellow blob) higher still
Top it off with the soprano (red blob) at the highest pitch

When the notes align properly, you'll hear a rich, harmonious chord!

4 Composing Melodies

Once you're comfortable with single chords, try creating movement:

Move one blob at a time to create a melody line
Let other blobs hold steady notes to provide harmonic support
Experiment with moving blobs in parallel (all moving up or down together)
Try contrary motion (some blobs moving up while others move down)

5 Recording and Sharing

When you've created something you're proud of:

Look for the record button in the Blob Opera interface
Press record and perform your composition
Stop recording when finished
Use the share feature to generate a link to your creation

Advanced Techniques

Creating Professional-Sounding Harmonies

To take your Blob Opera skills to the next level, try these advanced techniques:

Pro Tip: Use smooth, continuous movements rather than jerky jumps. This creates more natural-sounding phrases and prevents jarring transitions.

Voice Leading: Move each voice to the nearest available note in the next chord for smooth transitions
Dynamics: Create expression by varying the speed and smoothness of your gestures
Spacing: Leave appropriate gaps between voices - avoid bunching all blobs too close together
Vowel Modulation: Change vowel shapes mid-note to add color and interest

Common Intervals to Know

These musical intervals sound particularly pleasing in Blob Opera:

Octave: Two blobs singing the same note, one high and one low
Perfect Fifth: A stable, strong-sounding interval
Major Third: Creates a bright, happy sound
Minor Third: Adds a more somber, contemplative quality

Musical Ideas to Try

Rising Sequence: Have all four blobs move up gradually together, maintaining the same chord structure
Call and Response: Let one blob "ask a question" (rising melody) and another "answer" (falling melody)
Drone and Melody: Keep three blobs holding steady notes while one blob moves freely to create a melody
Canon/Round: Have each blob follow the same melodic pattern, but start at different times

Tips for Different Devices

On Desktop/Laptop

Use your mouse or trackpad for precise control
Click and hold while dragging for sustained notes
Use a larger screen for easier visualization of all four blobs

On Mobile/Tablet

Rotate to landscape mode for more control space
Use your index finger for the most precise control
Rest your device on a stable surface while recording
Consider using a stylus for extra precision on tablets

Common Mistakes to Avoid

Moving too fast: Rapid movements can sound chaotic. Slow, intentional gestures create better music
Ignoring the AI harmonization: The blobs automatically harmonize to some degree - work with this feature rather than against it
Overcrowding: Trying to do too much at once. Start simple and build complexity gradually
Forgetting vowel control: The left-right axis is just as important as pitch for creating expressive performances
