one of the great benefits of abc format is that tunes are portable and compact. I often email a blind fiddle player friend and she uses abcmus to play the tunes amazingly she is notating down tunes into abc herself and has gotten pretty good at it which is more than I can say. petr

It helps if you enter things properly. In the measure breaks, i was using /////////. That WILL make it too big to fit. You need to use ||||||| the upper case above the backward slash.

ABCMidi is a free program that will convert ABcs to midis or midis to abc.

ABCMidifier is a free program that will play your ABCs through the sound card and will also create a midi file of it.

You can find details of these and other programs for abc at the ABC Homepage

I have had great success in using ABC notation. To strip it down to the bare essentials:

ABC is a method of notating tunes that uses upper and lowercase letters to denote the notes. Slurs, ties, triplets, chords, and even bowing indications (for fiddlers)are easily shown. Of course, you need to learn the program before you can use it effectively!

ABC2Win is a program that will turn ABC notation into sheet music. Code must be entered correctly or sheet music won't print out properly.

ABCMus is a program that will play ABC notation so that you can hear the tune. Actually ABC2Win will do this too but not as well as ABCMus.

ABC notation works especially well for traditional tunes. It is not meant to incorporate all the symbols used in musical notation yet so some things can't be used with ABC. The few examples of this are not coming to my mind this morning, sorry.

With regard to slurs and ties - slurs are shown with the use of parentheses marks ( ) while the tie is shown with the use of the hyphen mark -.

Joe Offer; a slur means that all the notes within it are to be played smoothly, without any breaks between them (so it may cover a run of notes, for example). A tie joins notes of the same pitch; only the first one is played - it's a way of showing that a note is lengthened.

Hey Snuffy, Will try making the lines shorter. Maybe that will do it. I do know where the spin controls are....but i get the two above messages when i use them ("staff line...." and "draw note error 6....." sick of typing the whole message) I'm starting to wonder about the program. This is the first time that i've insisted on making it work since i bought it. I know it will be useful....once i crack the code!

Subject: RE: What is ABC format?

Sounds like you're on the music page trying to print out the dots. In this case notespacing refers to how the notes appear on the printout, not to the number of spaces you leave between notes when entering them as text. You alter this notespacing with the little spin controls at the bottom of the music page.

The printout part of abc2Win is not very good, and quite a few things will throw it - non-standard note lengths like G5/4 for instance. I think very long lines in the text input can also cause problems. I always start a new line every four measures or so to keep things manageable (It also helps you see where you are in the tune when reading it).

Don't give up, it's worth it when you finally crack the code.

Matt and I both put 1 space between notes unless we want them 'beamed'. OK, write all your code in notepad, save it as a txt file. Copy it, or select all and copy. Close the notepad file.

Open 2Win, and select New, all files, then exit that page. You should be back to a grey page--up top left is a button labled Tune. Click it, and choose Paste.......that should put your abc in the coded window. This is where you edit--fix mistakes at. Over on the far left, choose Draw 1, this should make notes out of your code. Select save,when prompted. It should now Play, and you can listen to see if it needs editing again.....or change speed, etc. If none of this works, PM Matt R, he is really good with the prog.

You do need a little bit of an introduction to set things up so your tune will play in an ABC player. Above are the basics.
The X line is the tune number, when you have a number of tunes in a document.
The T line is the title.
M is meter.
Can't recall if Q actually means quarter note, but that line designates the time value of a quarter note, and you can speed up or slow down the tune by varying the number. K is the Key.

So I added the stuff and tried to play it. It works, but I can't say I recognize the tune. Is it supposed to be something in particular??

Apparently some people can sight-read ABC just as well or better than sight-reading standard notation.

As far as getting chords, there are supposedly software packages that will suggest chords for a tune - ABCMus is one although I've never gotten it to work (perhaps because I don't have the registered version?). Putting chords to a tune is an art. Knowing a little music theory and experimenting is a good approach.

To answer your specific question, you have a line of music that appears to be in 4/4 time with a default note length of 1/8 note. Then: A,8| means the first measure consists of a whole note, A below middle C (the comma means below middle C). The second measure is a quarter note on F, an eight note on G, then F, then a quarter note on E, then two eight notes on E. All these notes are in the octave that starts with middle C. And so on. The vertical lines are bar lines. The numbers after letters are timing marks (you multiply the number by the default note length). Note that you should have some spaces between notes, otherwise the notes are considered to be "beamed" together. If you're running Windows, go to the ABC homepage (link on other thread) and download ABC2Win - it does a good job of drawing the standard music notation from ABC notation.

It may be worth noting here that you can include chord symbols in ABC at the appropriate point in the music by enclosing them in double quotes - for example, "Am7".

I think I figured out how to do ABC without relying on Alan's MIDITXT, but I can't get the slurs and ties right - partly because I always forget the difference between slurs and ties in real music. Anybody want to give me some pointers?
Those notes within parentheses are supposed to play all together, as one note held a long time. How do I do that, and what do I call it - a tie, or a slur?

c2c2B2A2|A2G4G2|GA3G2F2|E6G2|
D4F4|E4D4|(C8|C4)||

How do I show a dotted quarter note when my default note is a quarter? It would have been much easier to type this if I could have made the default note a quarter - but I couldn't, since did didn't know how to make a dotted quarter.
Oh, and I found out that a rest, appropriately, is the letter "Z" - if the default note is an eighth, then a quarter rest is Z2 - right?

This is great stuff - the best discussion I've seen on ABC. But have we answered the original question?

Is ABC the way to go to obtain chord progressions?

The raw ABC files don't contain chords - or at least I've never seen them. You can obtain a program such as ABCMUS to guess/extract them for you, but even as a registered user I have not been happy with many of the results.

I now have my own method of extracting chords from MIDI files, but it can be tedious, and the resultant chords are sometimes quite complex. What you get is what the original sequencing person inputs. (It's all too easy for a keyboard player to add the odd note here and there on the left hand to create what appears to be a formidable looking jazz chord). Prompted by a recent thread I've been looking at some Music Hall MIDI's, and like a lot of music originally designed for piano, the original chords are fantastic - if you like that sort of thing. If the occasion were to arise where i was to post these chords to this forum, should I edit them to be more folky or leave that to the individual reader?

Having said all this there is a large body of Celtic tunes on MIDI on the Web where the chords are relatively usable by the average guitar player. It seems however that the tools to make them visible are not so user friendly.

This sounds like a job for a bright, young programmer from Sydney who already has extensive experience in extracting data from MIDI files, and who is already familiar with the needs of Mudcat users. The suitable applicant should apply via this thread.

I think the easiest way to start (and I have not had time to devote to learning much in abc) is to choose a simple tune that you know, and look at the 'abc' for that tune. There are alot of websites on the net with abc tunes, which you can access from the abc home page. Play the tune as you look at the abc, and then all the symbols start to make sense. I refreshed another thread on abc tune search pages called 'ABC tune finder'.

With hopes that this is intelligible, I submit the following:

Basics of ABC. Notation is all in ASCII.

Notes:
The octave starting at middle C is denoted CDEFGAB, the next higher is c-b, then c' to a'. The octave below middle C is obtained by putting a comma after the letter, i.e., C,-- B,. For sharps, naturals, and flats preceed the note by ^, = or _, respectively. (You only have to do this for accidentals- see Key below for normal sharps and flats.)

Duration:
Indicated time 3/4, 4/4, 6/8, etc., (given after M:) all have a default normal note time which you can find explained in the file on the ABC homepage at 'abc standards'. This automatic default gave me too many surprises, so I don't usually use this default, but override it with an L:n specification, with n usually 1/8 or 1/4. Time multipliers and divisors start from the default note time.

With default note time = 1/4 then:
X2 duration is 1/4x2 or a half note
X3 duration is 1/4x3 which displays and plays as a dotted halfnote, etc.
x/2 is 1/2x1/4 = 1/8 note
x/4 is 1/4x1/4 = 1/16 note

put | to end a measure
\ indicates the tune continues, and not required at a typed line end, but I put it there to remind me what I originally typed up, (if for instance I look at it with an HTML browser), and I usually try to put the same number of measures in each typed line for ease of locating the position of an error discovered in proofreading the displayed tune.
Put ( ) around notes you want slurred.
Note times less than 1/4 note will have ties to the next note (if it's less a quarter note), unless you add a space between them, e.g. x3/4y/4 will have a tie bar between the notes but x3/4 y/4 won't

K: specifies keynote, but it really just tells the play program which notes are normally to be play as flat or sharp, and has no other effect. Major modes do not require anything other than the letter. For minor mode add m to keynote, and for others add dorian, mixolydian, etc., as required.

My ABC's then usually have a header:

X:n [specifies start of header of tune #n]
T:[Title]
S:[if you use this, info to be displayed]
Q:n [tempo, if you use this. There is also a default tempo which many times is ok]
L:n [if you use this]
M:n [n= 2/4, 3/4, 6/8, etc, timing]
K:X mode [Keynote and mode, if any]
xxx\ [tune code]
yyy\ [more tune code] ...
zzz] [End of tune code]

I usually signal end of tune by ], but this is not required

There's a lot more that you can find out about in the file downloaded from 'abc standards' [repeats, staccato, rolls, grace notes, and others], but the above gives the basics. And there's a lot more reference stuff you can put in a header with letters for information type coding, Z:xxx

With a little practice tune coding goes pretty fast, and the ASCII coded file for simple tunes runs 250-350 bytes, but lots more if there are a lot of grace notes, triplets, or dotted eighth-sixteenth note combinations.

I have to say that I still haven't caught on to the logic of ABC. Maybe there's just too much stuff to read at the ABC Home Page, and I get bleary-eyed and give up before the logic of it hits me. Anybody want to make a stab at typing up a clear, logical explanation of basic ABC - in 500 words or less? Can it be done?
What I do is cheat. I enter tunes on Noteworthy Composer, on an actual musical staff that I can understand. Then I create a MIDI from Noteworthy, and use Alan Foster's MIDITXT to post tunes here. Then I take the lazy way out and play the ABC version of tunes posted here, using my favorite ABC player, ABCMUS. If I really like a song, then I convert the posted version to a MIDI, using Alan's program.
Now if it took me all those words to explain how I do it the lazy way, can somebody actually come up with a clear, concise explanation of how to do it the right way?
