These ones represent whole notes, lasting for an entire measure of music. The previous example showed a string of ones, info = "1 1 1 1 1", of equal length (in terms of space-delimited entries in the character string) to the first argument giving a sequence of five C notes from different octaves. The most basic, and always required at a bare minimum, is the time duration of each note. LILYPOND TIES AND CHORDS CODEOther operators like this one to help shorten repetitive code are introduced later. Use this wherever convenient, though this tutorial section will continue to write things out explicitly for increased clarity. The second example here also shows the convenient multiplicative expansion operator * that can be used inside character strings passed to the three main phrase arguments. The following are equivalent, as shown when printing the LilyPond syntax generated by phrase. In fact, if you specify integer suffixes for octave numbering, phrase will reinterpret these for you. This notation is permitted by tabr as well. LilyPond markup uses single or multiple consecutive commas for lower octaves and single quote marks for higher octaves. It combines the note and the octave number to specify the pitch. This is the recommended way to specify notes. In the example here, what is likely intended might be "a2 b2 c3". But this may not be what you intend and there is no reason to assume anything. While it is allowable to specify note sequences such as "a b c", this assumes octave number 3. In special cases an abbreviated syntax is available, e.g., -^ or. This can be provided using the name in square brackets, e.g., or. There are additional single-note articulations that can be specified, such as accented or staccato notes. But with proper care they can be kept manageable and interpretable, depending on your comfort level with music theory, notation and R programming.īefore diving in, take a look at the tables below for an overview of some common syntax and operators that are used throughout this section. Phrases will become longer and more visually complex. This section will cover phrases that include notes and rests of different duration, slides, hammer ons and pull offs, simple string bends, and various other elements. The opening section showed a basic example using a single, and very simple, phrase. While the API is far more limited than writing LilyPond markup directly, generating music notation programmatically and creating sheet music dynamically is an entirely different use case from writing markup for a specific song. Working from a programming language like R is also very different from writing static markup files. The motivation for tabr is primarily music data analysis from a notation perspective, but to the degree that various types of notation are supported, it also allows you to transcribe your data to sheet music or tablature. You can always write LilyPond markup directly and this will give you more options and greater control. Writing music notation in R code is not intended to replace LilyPond markup. They should also represent meaningful or convenient segments of music, for example whole measures, a particular rhythm section, or an identifiable section of a longer solo. It is recommended to keep phrases short enough that they do not too much cognitive load. LILYPOND TIES AND CHORDS HOW TOIt also describes how to add note information to the notes in a phrase.Īs mentioned in the last section, “phrase” in tabr does not require a strict definition. This section goes into deeper detail on building musical phrases out of individual notes using the syntax available for phrase construction.
