I started on 'cello so it is second nature to me. I would maybe try getting some 'cello (or similar bass clef instruments) music and playing that with just your left hand to practice your reading on bass clef. Also (many will strongly disagree) I would advise getting into the theory. It will help your familiarity with the various clefs. I will let you in a secret: When sight reading something like classical music you can almost make it up based on what you expect is going to happen. I remember playing a piece once and there was a truly horrible 4 bar section for the double basses which we had no time to learn (one of those rehearse in the day, concert in the evening jobs). Basically I knew which note is started on, that the intervening notes were mostly scalar runs in key and which note it finished on finished on and the direction of the movement. So you just went for it, you weren't reading each note as it came, you didn't have time! We just used to look at each other and say "see you at the other side!". It was close enough that even the conductor didn't notice so... And if it is modern music more often than not no-one knows what it should sound like anyway so .... ;)

You've just got to work on it. Maybe get some musical flash cards and work on trying to say the bass-clef note names as fast as possible.

Try this game: http://courses.wcupa.edu/frichmon/usetech/musicalflashcards/bcnotes.html Another little tidbit to know is that all the notes are 2 notes higher than on the treble clef. For example, when you read middle C on the treble clef, the same line on the bass clef is E. Sorry if that just made it more confusing! As with mostly anything, practice helps the most.

Sight read as much as you can, even if you have to take it slowly at first. I use a book of Bach Chorales and sight read a couple a week, and I've seen dramatic improvement in my ability to read.

Bass clef shortcuts - spaces starting from the bottom -All Cows Eat Grass. Lines starting from the bottom - Good Boys Deserve Football Always - OR - Green Buses Drive Fast Always. You just have to learn them! Good luck.

Sight reading as Ender said. Just grab a bunch of books...Real Books...anything and read through them slowly. Don't try and learn each piece. Go through one, then the next, then the next....so on just reading the bass clef.

site read whilst saying the notes out loud when you play - it helps you memorise them more, this is the best way to commit the notes to memory. And for the purpose of learning the notes its not best to guess the notes - really look at what you are reading.

If you know the notes in the treble well, then a good thing to know would be that the notes are moved two notes down in the bass. What I mean is, say you have a C6 (the C an octave above middle C)....it is on the third space of the treble (always count from the bottom up). Now, all you have to do to find a C in the base (in this case, C4) and move that C to the space below it, the second space. That is a C in the bass. However, this is not the best method. The way I learned was to simply memorize the position of at least one note on the bass staff, and from there counting up the scale as needed until I found the notes. I did this for a short time until I memorized the whole staff. In my case I chose C4, but I would suggest F4 instead. This is because the bass clef, or the F clef, shows you where F4 is, just like the treble clef, or G clef, shows you where G5 is. In the bass staff, F4 is between the two dots of the bass clef.

What I do is look at the staff and memorize one note at a time. I stare at a note for a long time, learn it, think it, eat it, breath it, and then I try another one. By doing this, I can have kind of a landmark note then I can work my way up memorizing other ones.

I am teaching a beginner on the piano who is working on the bass clef. There are some very good answers above and I agree that it is a matter of seeing the notes again and again and linking the note on the stave to its name and to the note on the piano. One note that might be easy to learn first is middle C. That note can be shown on the ledger line immediately below the stave in the treble or it can be shown on the ledger line just above the stave in the bass. When you have learned a few notes it should become easier to fill in the gaps between them. As a way of remembering the lines in the bass, starting from the bottom, I have heard: Grizzly Bears Don't Fear Anything giving GBDFE.
