To make your app capable of creating small tunes for ear training, you can add features that generate and play random or user-defined sequences of swaras. Here's how you can approach it:

New Features for Ear Training

1. Generate Random Swara Sequences

Add a feature to generate random sequences of swaras like |S R G M | P D N S'|.

Display the sequence after it is played, allowing users to identify the swaras by ear.


2. Playback Custom Sequences

Let users input their own sequence of swaras and play it back for ear training.


3. Ear Training Modes

Listening Mode: The app plays a sequence, and the user identifies it.

Input Mode: The app provides a swara (e.g., "Sa"), and the user plays the correct key.

Steps to Implement Ear Training

1. Random Sequence Generator

Use a randomizer to create a sequence of swaras:

val swaras = listOf("S", "R", "G", "M", "P", "D", "N", "S'")
val randomSequence = (1..8).map { swaras.random() }


2. Play the Sequence

Loop through the random sequence and play the corresponding sound:

randomSequence.forEach { swara ->
    when (swara) {
        "S" -> soundPool.play(saSound, 1.0f, 1.0f, 1, 0, 1.0f)
        "R" -> soundPool.play(reSound, 1.0f, 1.0f, 1, 0, 1.0f)
        // Add cases for other swaras
    }
    Thread.sleep(500) // Delay between notes
}


3. User Input Mode

Allow users to input a sequence via an on-screen keyboard or buttons:

val userInput = mutableListOf<String>()

keyC.setOnClickListener { userInput.add("S") }
keyD.setOnClickListener { userInput.add("R") }
// Add listeners for other keys

Compare the user's input with the generated sequence:

if (userInput == randomSequence) {
    textView.text = "Correct!"
} else {
    textView.text = "Try Again!"
}


4. Custom Sequence Input

Create a text field where users can type their own sequence (e.g., "S R G M P").

Parse the input and play the corresponding sounds:

val customSequence = inputEditText.text.toString().split(" ")
customSequence.forEach { swara ->
    // Play corresponding sound
}


5. Display Notation

Display the generated or custom sequence on the screen for reference:

textView.text = randomSequence.joinToString(" ")



---

UI Design

Add buttons for "Generate Tune" and "Play Sequence."

Include a keyboard interface for input mode.

Add a TextView to display sequences.



---

Testing and Refinements

Ensure the delay between notes matches the desired tempo.

Adjust sound quality and volume for clarity.

Test the random generator to avoid repetitive patterns.
