Installationĭownload the official JFugue library (the current version is 5.0.9) and add the JAR file to your java project as an external library.Īlternatively, if you're using Maven, you can download the dependency through your pom.xml file. While it is not strictly required, basic musical knowledge would help you more quickly understand some of the musical concepts referred to in the article. Since we are going to work with MIDI, an audio output device (speakers or headphones) will be needed to observe the results. Let's start by preparing our development environment. JFugue Beginners Guide Part III: Rhythms, Reading and Writing to MIDI.JFugue Beginners Guide Part II: Chords and Chord Progressions.This method requires a single parameter i.e. JFugue Beginners Guide Part I: Notes, Durations, Patterns (you're here) Two durations can be compared using the compareTo() method in the Duration class in Java.
#Java compare durations how to#
In the final part, we will also take a look at how to save our music to a MIDI file using the JFugue as well as read music from a MIDI file using the JFugue library: By using our previous knowledge, we will be able to finalize the intro of our song. To compare the performance difference caused by this change, there is one Lambda function with the additional changes and one without. The application is triggered by Amazon API Gateway and then puts an item into Amazon DynamoDB. In the third and final part of the series, we will learn about Rhythms in JFugue. The example project is a Java 11-based application used to analyze the impact of this change. We will learn how to use setKey(), distribute() and allChordsAs()methods of the ChordProgression class.
For instance, the modified duration of a 5-year, 8 annual payment bond is 3.786. In the second part of the series, we will explore how to create and manipulate chords and chord progressions in Jfugue. The calculation of the Modified Duration (ModDur) statistic of a bond requires a simple adjustment to Macaulay Duration as such: M odDur M acDur (1+y) M o d D u r M a c D u r ( 1 + y) Where y yield to maturity or required yield. Doing so we will be able to re-create a small part of the vocals of the jazz version of Sunday Morning by Maroon 5. In this guide, we will focus on the most fundamental parts of the JFugue library by learning about the notes, octaves, durations, tempo, instruments, and patterns. This is going to be the first part of the three-part series. It is within about 1 second of mean solar time. By using JFugue, you can convert the Staccato strings into a MIDI file, as well as import a MIDI file, and convert the content into human-readable strings. Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It uses their "Staccato" format to parse strings of musical instructions. String dateStart ' 08:29:58' String dateStop ' 11:31:48' //HH converts hour in 24 hours format (0-23), day calculation SimpleDateFormat format new SimpleDateFormat('MM/dd/yyyy HH:mm:ss') Date d1 null Date d2 null d1 format.parse(dateStart) d2 format.parse(dateStop) //in milliseconds long diff d2.getTime() - d1.getTime() long diffSeconds diff / 1000. JFugue is an open-source Music library that allows you to play and compose MIDI music using the Java programming language.
