    }
}

Code Output:

The expected output when this Java program is run is an audible sequence of MIDI music. Initially, it plays a simple chord progression using a C Major chord, followed by a sequential melody based on the C Major scale. The chord progression consists of four repetitions of the C Major chord (C, E, G) with each note held for two beats. After the chord progression, an eight-note melody is played sequentially with each note from the C Major scale held for one beat. This output runs for approximately 10 seconds before the program ends and the music stops.

Code Explanation:

Here’s how the magic happens. First off, the code kicks off by setting up a MIDI sequencer and creates a new MIDI sequence with a Pulses Per Quarter note (PPQ) timing division and a resolution of 4 ticks per beat. A separate track is created within the sequence to hold our musical events.

The program defines a simple C Major chord and sets the music’s tempo as 120 BPM. Using a loop, it schedules MIDI events to play each note of the chord progression. A ‘Note On’ event signals the start of a note, while a ‘Note Off’ event ends it. The notes are repeated over four bars, with each chord lasting two beats. Next in line, a melody is constructed from the notes of a C Major scale and spread across eight beats.

A MetaMessage binds everything together by setting the sequencer’s tempo with our predefined BPM. To let the notes ring out, the program concludes by starting the sequencer, pausing the thread to sustain the music for 10 seconds, and then stopping the sequencer.

This neat block of code doesn’t just randomly spit out sounds; it crafts an algorithmic symphony that warms the circuits of my programmer’s heart. Hope y’all enjoy listening to it as much as I enjoyed writing it! Keep coding, and keep the music playing. 🎶

Thank you for reading, folks! Never forget, code is poetry and every programmer is a bit of a poet. Keep jamming with those keys! 🚀✨
